Environment: Private cloud of Exchange services for a client
- Forest "a.cloud" contains forest controller 1.a.cloud and exchange server "ex.a.cloud"
- domain "x.cloud" is child domain in forest "a.cloud"
- client domain "x.local" replicates groups, users and passwords to domain "x.cloud"
- Exchange server has a "split permissions" configuration: the users are created in client AD and after the replication, the client creates the mailbox in EMC.
Problem: in the last days two users appears in "Mailbox" and "Disconnected Mailbox" without ANY intervention (i.e. move between datastores, AD user modification, etc). Where can i see the reason of mailbox disconnection ? I see when this happened, but i can't see anywhere in event viewer why this happened.
Yesterday I deleted and recreated one of them and today his mailbox is again in both places. "clean-mailboxdatabase" doesn't help...
