After a mailbox is moved from an Exchange 2003 server to an Exchange 2007 server the user may find they are unable to logon to Outlook even after the mailbox move wizard has completed. The Exchange server will log the following events at the completion of the wizard:
Event Type: Information
Event Source: Exchange Migration
Event Category: Move Mailbox
Event ID: 1007
Date: 16/08/2007
Time: 14:24:48
User: N/A
Computer: SERVER
Description:
Mailbox ‘John Smith’ has been moved.
Event Type: Information
Event Source: Exchange Migration
Event Category: Move Mailbox
Event ID: 9354
Date: 16/08/2007
Time: 14:25:01
User: N/A
Computer: SERVER
Description:
Mailbox ‘CN=John Smith,OU=USERS,DC=domain,DC=local’ is deleted from the Exchange store ‘CN=Mail Store,CN=First Storage Group,CN=InformationStore,CN=EXCHANGE2003SERVER,CN=Servers, CN=First Administrative Group, CN=Administrative Groups,CN=Exchange Organisation,CN=Microsoft Exchange,CN=Services, CN=Configuration,DC=domain,DC=local’ on server ‘exchange2003server.domain.local’.
Though the mailbox move wizard has finished the mailbox is not yet ready for logons. The Exchange server performs some processing of the mailbox after the move, and depending on the size of the mailbox and the load on the server at the time this can take a while. As a general rule I advise users of a delay of up to 30 minutes after a mailbox move is complete before the mailbox is ready for logons, although in the vast majority of cases it is ready after only a few moments.
The Exchange server will log the following event when it is finished processing the mailbox.
