Cause
Source mailbox in question has either been recently created or moved from one mailbox database to another and thus is not present in MMEX SQL database. -
Resolution
To resolve the issue:
1) Expand the Source Exchange Organizations node in MMEX Management Tree down to the source Exchange server.
2) Right-clcik the source Exchange server in the Tree and select Refresh command from the shortcut menu.
Refreshing the source server data should add a problem mailbox to MMEX SQL database and MAgE will be able to synchronize it.
