Title
"ERROR: [1249-53-6-00000000] User has no mailbox" -
Description
When attempting to migrate user's mail into Exchange, the migration fails and ther following error is received:
[1249-53-6-00000000] User has no mailbox
-
Cause
Either the user's mailbox does not exist in Exchange (or is not reachable), or the targetAddress value in the NME database does not match what currently exists in Exchange, therefore it does not 'exist' to the migration software.
-
Resolution
Confirm you can open the user's mailbox using Outlook, and that the Exchange mailbox address is a match for the target SMTP address value in the NME database.
