We have a Single Forest.. multiple domain child domain scenario. In one of our child
domain we are upgrading from exchange 2010 to exchange 2013. After exchange
2013 server deployment we been trying to move mailbox (from 2010 to 2013) but
it fails with Error " MigrationTransientException: Failed to communicate with the mailbox database. --> Failed to communicate with the mailbox database. -->MapiExceptionNetworkError: Unable
to make connection to the server.
?(hr=0x80004005, ec=2423)" But if we try the same using Management Shell (i.e.New-MoveRequest -Identity‘abc@xyz.com -TargetDatabase "TEMPDB"-BadItemLimit 100) itscompleting successfully.
Need help.
