XFOR: Exchange and Internet Mail Client Co-existence
ID: Q193930

The information in this article applies to:
-
Microsoft Exchange Server, versions 5.0, 5.5
SUMMARY
Customers want to maintain connectivity and co-existence with both Internet
Mail/POP3 and Exchange Server services, but they do not want the users to
be able to select Exchange Server users from the global address list (GAL).
For example, users are using Microsoft Outlook 97 as their client. They
have two services for each profile: Internet Mail Service and an Exchange
Server service. Also, each user has two SMTP aliases: Internet Mail/POP3
system (for example, Adam) and another for Exchange Server (for example
Adam.Barr).
To enable this functionality, create alternate recipients for each Exchange
Server mailbox, and hide the Exchange Server mailbox, by following these
steps:
- Create a custom recipient (CR) that maps to each user's alias on the
POP3 system (for example, a CR whose SMTP address would be
Adam@acme.microsoft.com).
- In the Properties for each native Exchange Server recipient, select the
Delivery Options tab, and under Alternate Recipients, click the option
button next to the text field, and click Modify. Select the CR you
created in Step 1, and click OK.
- While still in the recipient's Properties, select the Advanced tab, and
clear the "Hide from address book" check box. Click OK.
The net effect of this is that the Exchange Server recipients do not appear
in the GAL (so they can't be selected from within the organization). Also,
any mail accidentally sent to the Exchange Server mailbox gets
copied/forwarded to the alternate recipient, which just happens to be the
user's POP3 mailbox. Additionally, hiding the Exchange Server mailbox from
the address book does not affect inbound routing of messages from other
systems.
Now, administrators can migrate users to Exchange Server on a user-by-user
basis. As users are migrated, simply remove the CR, unhide the mailbox, and
switch "Alternate Recipient" back to "None."
