Error: [ErrorNonExistentMailbox]

Problem:

You get the following error in CodeTwo Exchange Migration or CodeTwo Office 365 Migration:

[ErrorNonExistentMailbox] - The SMTP address has no mailbox associated with it.

Solution:

• The target mailbox is not fully enabled. A user must log in to the OWA and go through the initial mailbox configuration (define regional settings).
• You have accidentally pointed at wrong target server.
• You have deleted or disabled/locked the mailbox on the target server or removed the SMTP address in question from it.
• Target server domain is improperly configured at your domain registrar (e.g. points at old server).
• Your source server side DNS forwards target domain queries somewhere else.
