In this chapter, you learn how to establish a messaging link between Microsoft Exchange and a Macintosh server running Microsoft Mail for AppleTalk networks. Unlike a MS Mail for PC networks, MS Mail (AppleTalk) does not use the postoffice paradigm. Therefore, the process for connecting to an Exchange server is somewhat different. With respect to the Macinstosh side,the Macintosh server believes it is communicating with a standard MS Mail (PC) postoffice. MS Mail for AppleTalk uses a special gateway component to communicate with the Exchange MS Mail Connector. With respect to the Exchange side,the Microsoft Mail Connector has specific configuration settings, and message queue for MS Mail (AppleTalk) connections. Any configuration specifically pertaining to Exchange communicating with MS Mail Postoffices is not applicable.
In this chapter, you learn the following:
Introduction to the Microsoft Mail Connector
In this section, you learn about the conectors used to establish a link between Exchange and Microsoft Mail (AppleTalk) servers.
The two core Exchange Microsoft Mail Connector components are the same:
Exchange also includes one additional component for communication with MS Mail (AppleTalk) servers:
The following details the procedure for connecting Exchange to a Microsoft Mail for AppleTalk networks:
1. Set up all necessary network connections between systems.
2. Install and set up the Exchange Microsoft Mail connector.
3. Place the Connector postoffice on a Macintosh accessible NTFS volume.
4. Configure the Exchange MS Mail connector to communicate with MS Mail (AppleTalk) servers. This includes starting the MS Mail (AppleTalk) MTA service.
5. Install and configure the Microsoft Exchange Connection software on the MS Mail (AppleTalk) gateway server.
6. Enter address space entries for the MS (AppleTalk) server. Test for correct message routing between systems.
7. If you want additional MS Mail (AppleTalk) servers to communicate indirectly with the Exchange server, install and configure the gateway access component on each Macintosh server.
8. Test transfer of messages to indirectly connected MS Mail (AppleTalk) servers if applicable.
9. Once messages are routed properly to all servers, proceed to set up directory synchronization to maintain up-to-date address lists among systems.
Installing Services for Macintosh
The following steps help you to configure your Exchange server to support Microsoft Mail for AppleTalk networks. Windows NT Services for Macintosh enable your server to communicate over Apple's native AppleTalk protocol. You must have an NTFS partitioned hard disk to support Services for Macintosh.
The following steps are quick guidelines to help you set up NT services for Macintosh. Consult your Windows NT Server documentation for more advanced configuration information.
1. Open the Network control panel on your Windows NT server. The Network Settings control panel appears (see fig. 19.1):
The Windows NT Network Control Panel is part of your Windows NT server.
2. If Services For Macintosh is not listed in the Installed Network Software scroll box, it is not installed. Click Add Software. The Add Network Software dialog box appears (see fig. 19.2):
Select Services For Macintosh among the list of available components.
3. Select Services For Macintosh from the list of available network software. Click Continue.
4. Type the directory path to your Windows NT server software, for example, CD-ROM, floppy disk, or server volume. Click Continue.
5. After the services are loaded from disk and installed, you will return to the Network Settings control panel. Services for Macintosh should now be on the Installed Network Software list.
6. Click OK to complete service installation.
7. You will be prompted to restart your server to update the Network settings.
8. Click Restart Now if this is appropriate. Alternatively, you can click Don't Restart Now to return to the Windows NT program manager.
If you choose not to restart immediately, remember that you will have to do so before continuing with Exchange to MS Mail (AppleTalk) configuration.
A Macintosh Accessible Volume must be created so that your MS Mail AppleTalk server is capable of seeing your Exchange server on the network. Then, the two systems can trade messaging data. The volume itself is a directory within the NTFS structure configured for connection from a Macintosh. The Macintosh server will be configured to automatically log on to this volume on start-up.
The following steps show you how to create and configure a Macintosh Accessible Volume:
For more information on Macintosh Accessible Volumes, refer to your Windows NT Server documentation.
1. Open the Windows NT file manager.
2. From the file manager, you can find the following folder.
3. :\EXCHSRVR\CONNECT\MSCON\MAILDATA
This assumes that you have named the main Exchange directory "EXCHSRVR" during installation.
4. From the MacFile menu, select Create Volume. The Create Macintosh-Accessible Volume dialog box appears (see fig. 19.3):
You can create a New Macintosh Accessible Volume from the MacFile menu.
5. The Volume Name should be "MAILDATA."
6. You can enter a Password once. Then, you can enter it again in Confirm Password. The Macintosh server must use this information to connect to this volume. By default, no volume password is entered.
7. For enhanced security, clear the Guests Can Use This Volume checkbox.
8. Confirm that This volume Read-Only remains unchecked.
9. Be sure that the Unlimited User Limit radio button is selected.
10. Click OK to create this volume and return to the file manager. Better yet, click the Permissions button to set access rights to this volume.
After creating a Macintosh Accessible Volume you must define what users and groups have permission to access it. This is done in the Macintosh Accessible Volume Permissions dialog box. This dialog box is almost identical to the Macintosh File Sharing dialog box. In this box, you select the Windows NT accounts that have access rights to this volume. The following steps will guide you in setting access rights to this volume:
1. There are two ways to open the permissions for a Macintosh Accessible Volume. You can do this by clicking Permissions from the Create Macintosh-Accessible Volume dialog. Alternatively, you can select the Volume from the file manager. Then, select Permissions from the MacFile menu. The Macintosh View of Directory Permissions dialog box appears (see fig. 19.4):
You can set access permission for this volume.
2. Use the...(ellipses) buttons to configure an Owner and Primary Group for this volume. These determine who is able to connect to this volume through the Macintosh Chooser.
3. Confirm that See Files, See Folders, and Make Changes permissions remain checked for the Owner and Primary Group.
4. Clear the check boxes pertaining to Everyone. This prevents anyone, except those users contained in Owner and Primary Group, from using this volume. By default, the Everyone permissions are checked.
5. Select the Replace Permissions On Subdirectories check box. This gives all directories within the current one permission settings identical to the ones on this page. By default, this box is not checked.
6. Click OK to set these permissions and return to the file manager.
You have completed the Macintosh Accessible Volume configuration. This directory is now available for connection through the Macintosh Chooser. To confirm accessibility, you can test a manual connection, using the following steps:
1. Open the Chooser application from your Macintosh's Apple menu.
2. Click AppleShare icon in the Chooser. Then, select the AppleTalk Zone, if applicable, in which your Exchange server is located.
3. The Exchange server should now be listed in the Select A File Server display window.
4. Click the server's name. Then click OK.
5. On the connect dialog box, make sure the Registered User radio button is selected. Enter the user Name and Password for this server. Then, click OK.
6. After your are authenticated, a list of available Macintosh Accessible Volumes displays in the Select The Items You Want To Use: window.
7. Your newly created "MAILDATA" (or whatever customized name you chose) volume should appear on the list.
8. If your Volume is not visible, repeat the preceding steps for creating and configuring a Macintosh Accessible Volume. Otherwise, proceed to the following section.
Configuring The Mail Connector for Use with MS Mail (AppleTalk)
Now that connectivity between Macintosh and Windows NT server has been established, the next step is to set up the Exchange MS Mail Connector to send and receive messages with the MS Mail (AppleTalk) server.
The following list details the property pages for the Exchange MS Mail connector. This list also discusses how they are configured to work with AppleTalk networks.
Configuring Exchange MS Mail Connector Properties
This section covers the installation of Microsoft Mail Connector properties primarily corresponding to communication with MS Mail (AppleTalk) servers. For a complete guide to the MS Mail connector, see Chapter 18.
The following steps guide you through the Interchange configuration:
1. Open the Microsoft Mail Connector property pages.
2. Select the Interchange tab. The MS Mail Connector (BOSTON01) Properties page appears(see fig. 19.5):
You can designate mailboxes to be used by the MS Mail Connector Interchange property page.
3. You must set an administrator's mailbox if one has not already been defined. It will receive status notification from MS Mail Connector. If one is not defined, click Change. Then, select a mailbox from the address list.
For a larger organization, it is a good idea to create a POSTMASTER account to receive the potentially large volume of status messages. This way, one administrator mailbox will not be burdened with an extra message load. Also, other administrators can view the delivery messages without logging on to a general administrator mailbox, or somebody else's personal mail.
4. Select the Primary Language For Clients from the pull-down menu.
5. Check the Maximize MS Mail 3.X Compatibility box to provide for OLE objects embedded in Exchange messages.
6. Unless you are currently using message tracking for troubleshooting purposes, make sure the Enable Message Tracking check box is cleared. For more information on message tracking for troubleshooting purposes, see Chapter 26, "Troubleshooting Exchange's Directory Services."
7. Configure the AppleTalk MTA settings. The following section discusses these settings.
You can open a messaging link between Exchange and MS Mail (AppleTalk). To do this, you enable the MS Mail Connector AppleTalk message transfer agent by following these steps:
1. Click the Configure button under the MS Mail Connector (AppleTalk) MTA. The MS Mail Connector (Apple Talk) MTA Options dialog box appears (see fig. 19.6):
You can view and set MS Mail (AppleTalk) MTA service status.
2. Select the Enable MS Mail Connector AppleTalk MTA radio button under the Set Status window.
Enabling the AppleTalk MTA adds to the list of services in the Windows NT Services control panel.
3. Select the Start Automatically At System Startup radio button to configure this option. By default, this option is selected. Click OK to return to the Interchange property page.
Normally, you will always set the AppleTalk MTA service for automatic startup. If, for example, you have a situation that requires some troubleshooting, and you want to have complete manual control over this service, select the Manual Start radio button.
4. Click Apply to set these properties and continue with other ones. When you are finished with all settings, click OK set them and to return to the Administrator Program.
The Local Postoffice information identifies the Microsoft Mail Connector Postoffice to the Macintosh MS Mail (AppleTalk) servers and any MS Mail Postoffices on the network.
1. Select the Local Postoffice tab from the MS Mail connector property pages. The MS Mail Connector (BOSTON01) Properties page appears (see fig. 19.7):
You can configure the local MS Mail Connector postoffice information.
2. Enter the MS Mail Network name for this postoffice. By default, this is the Microsoft Exchange organization name.
3. Enter a Postoffice used to identify this connector to other MS Mail servers. By default, this is the Exchange server's name.
4. Enter a Sign-on Password used to authenticate other mail systems. By default, this is set to PASSWORD. You should change it for security reasons.
5. If you make any changes to postoffice settings, click Regenerate to rebuild addressing data.
For Local Postoffice information changes to take effect immediately, you must restart the Connector Interchange service as well as the MS Mail MTAs.
6. Click Apply to set these properties and continue with other ones. When you are finished with all settings, click OK to set them return to the Administrator Program.
The Connections property page only gives you the option of viewing the Microsoft Mail (AppleTalk) MTA message queue. The other options, such as Modify, Delete, and Create, are available only for Microsoft Mail (PC) connections. The MTA queue lists all outgoing messages awaiting transmission by the MS Mail AppleTalk message transfer agent.
To view the MS Mail (AppleTalk) MTA message queue, follow these steps:
1. Select the Connections tab from the MS Mail connector property pages. The MS Mail Connector (BOSTON01) Properties page appears (see fig. 19.8):
You use this page to view the MS Mail connector AppleTalk message queue.
2. The Connections display window shows all current MS Mail connections.
3. Click the AppleTalk Mail entry in the window. The Modify and Delete buttons will dim.
4. Click the Queue button to bring up the Messages queued for Apple Talk Mail dialog box (see fig. 19.9):
The MS Mail (AppleTalk) message queue shows all the pertinent information on current messages.
5. The Queued Messages window shows the current messages awaiting delivery by this MTA.
From The message sender
Subject The information on the message's subject
line
Message ID The Exchange message identification code
Date/Time The time the message entered the queue
6. Click Refresh to update the message list .
The queued messages window is a listing of messages awaiting delivery at that moment. To get a more dynamic view of messages passing through the connector, you must repeatedly click the Refresh button. Clicking this button also gives you the latest updates.
7. Select a message. Then, click Delete to remove it from the queue. If Send Non-Delivery Reports When Messages Are Deleted is checked, the message sender will be notified of the deletion.
8. Select a message. Then, click Return to remove a message from the queue and return it to the sender.

9. Select the check box to the right of the Maildata volume to have this volume automatically mounted every time the Macintosh server starts up.
10. Select the Save My Name Only radio button to request your password when the volume attempts to mount at startup.
11. Select Save My Name And Password to store your log-on data and then automatically authenticate your connection when the Macintosh starts up.
12. Click OK to mount the volume.
The Exchange Connection Gateway is provided with your Microsoft Mail Connector software. Install it on your Macintosh MS Mail server to allow it to connect to the Exchange connector postoffice.
The following section assumes you have Microsoft Mail for AppleTalk Networks installed and properly running on your Macintosh server.
The following steps guide you through installing the Connection Gateway on your Macintosh server.
1. Log on to your MS Mail (AppleTalk) server as Network Manager.
2. Load the disk containing the Exchange Connection Installer. Open the installer application. The Connection Installer dialog box appears (see fig. 19.10):
View the installed gateways. This appears blank if there are none.
3. If no previous gateways have been installed, the Gateways Installed on This Server: window appears blank.
4. Select Install Gateway from the Gateway menu.
5. Select the GW icon from the dialog box. Then, click Install. The dialog box in figure 19.11 appears:
You can enter Gateway Identification Information using this dialog box.
6. Enter a unique Gateway ID. This identifier is used by the MS Mail (AppleTalk) server to distinguish each gateway. By default, the ID for this gateway is NC.
7. Enter a Gateway name as it will be displayed in the gateway list. Click OK. The dialog box in figure 19.12 appears:
You use this Gateway template to create external addresses.
8. Select which gateway templates to install for this gateway. Choose only those that you can access through this gateway, for example, those you use in your Exchange organization. Click OK.
A gateway template becomes available in your MS Mail (AppleTalk) client to create custom recipient for other messaging systems.
The Gateway is installed. Now, switch to your Microsoft Mail (AppleTalk) client which should still be logged in as Network Manager.
With the MS Mail (AppleTalk) client, you now need to configure various gateway and postoffice connection options.
You must be logged in as Network Manager to administer a MS Mail (AppleTalk) server.
Specify the postoffice location and general gateway configuration by following these steps:
1. Select Gateway. Then, select Configuration from the Mail menu.
2. A dialog prompts you to locate the Connection Store (MacGate) directory. Click OK.
3. Scroll through the MAILDATA volume and locate the MACGATE folder. Click Open.
4. Enter a Blocking Factor value. This value limits the number of messages that can be transferred with each gateway cycle.
5. Enter an Aging Factor value. This is the amount of time, in minutes, that a message can remain in the MS Mail Connector postoffice before a notification message is sent to the Network Manager.
Setting the Aging Factor to zero turns off notification.
6. Set the Max Size value. Messages exceeding this size (including attachments) cannot pass through this gateway. By default, this size is 100 kilobytes.
7. Select a logging level for this gateway. Select one of the three radio buttons: Critical, Errors, or Details.
This screen is functionally similar to Exchange’s schedule property pages. Use this dialog box to configure at what times during the day this gateway connects to the MS Mail Connector postoffice. Your decision for the time of the day the gateway is to connect to the MS Mail Connector postoffice should be based on factors particular to your situation. For most, bandwidth, server loads, and connection costs (for example, over leased lines, or ISDN) are the limiting factors in this decision. If bandwidth or line costs are not an issue in your case, set the connection times as frequently as you want.
To set connection times, follow these steps:
1. Select Gateway. Then, select Connect Times from the Mail menu. A schedule gride appears for you to set connection times.
2. Select the radio button that determines how frequently you want this
gateway to initiate connection.
The Never button effectively deactivates the gateway.
The Always button connects at the interval (in minutes) set at the
bottom of this dialog box.
At The Times Selected In The Chart Below defines connection times by
those that are highlighted in the time grid.
3. Select the Connect Immediately When There Is Outgoing Mail check box to initiate a gateway connection as soon as a message is sent to to the gateway.
4. If you chose the Selected Times option, use the time grid to mark the specific time you want the gateway to connect and transfer messages.
After you have installed and configured the Connection Gateway, you can install additional access gateways on your MS Mail (AppleTalk) system. This enables other Macintosh MS Mail servers to communicate with Exchange and all its gateways and connectors.
You install an Access Connection Gateway by following these two steps:
For step-by-step procedures for additional gateway installation, consult your gateway documentation.
From Here...
The information in this chapter bridged two disctint mail environments (Exchange and MS Mail for Appletalk) with some external tools. However, most likely this will be just the first step in a full migration of Macinstosh users onto Exchange. The upcoming release of a Macintosh Exchange client will provide for a better alternative for bringing Macintosh users onto an Exchange environment. As of this writing, the Macintosh client is in preliminary beta and will become release product in the next two to three months.
