XFOR: SFS Mail Not Migrated When Custom Recipient Is Converted

• Microsoft Exchange Server, version 5.5

SYMPTOMS

When you migrate a user from Microsoft Mail to Microsoft Exchange Server using the Exchange Migration wizard, and a custom recipient for the user being migrated already exists, the following event may be logged and the user's data may not be migrated properly:

   Event ID:      7026
   Source:        MSExchangeMig
   Type:          Error
   Category:      None
   Description:   Migration Aborted due to Mapi logon failure. 

CAUSE

When a user is migrated from Microsoft Mail to Exchange Server and a custom recipient is found with the same "MS" proxy address, that custom recipient is converted to an Exchange Server mailbox to preserve proxy addresses.

Through this code path, "MIGRATE" proxy is not created.

The "MIGRATE" proxy is used to find the mailbox when migrating the user's information (schedule information, e-mail, and so on).

RESOLUTION

The Exchange Migration wizard now searches for the "MS" proxy as well as the "MIGRATE" proxy to find the mailbox.

STATUS

Microsoft has confirmed this to be a problem in Exchange Server version 5.5. This problem was corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.5.
