Why is the Microsoft Exchange Migration tool sending mailboxes to a database other than the one I select?
Posted on 2015-01-18
When using the MS Exchange Migration tool through the Exchange Admin center (http interface) to move mailboxes, the migration tool sent the mailbox to a completely different database than the one selected. We have three databases, db1, db2, and spamdb. We are moving servers to a datacenter offsite. DB1 and SPAMDB are local to each other (i.e. on the same server) and DB2 is the datacenter. All mailboxes are on DB1.
When I migrated mailboxes to DB2, some actually went and others went to the SPAMDB. Now, when I individually select the mailboxes in SPAMDB to migration to DB2, it tells me it migrated fine but I look and they're all still on SPAMDB.
