Hi,
We are using exchange 2013 CU3 in our environment, When we try to connect to a disconnected mailbox using EAC or powershell it gets succeeds for Primary mailbox however if I try the same way to connect archive mailbox it throws me a error "The legacy DN is already in use by following active directory user " Primary mailbox User name". The vaule Legacy DN must be unique to each other
can anyone help me in this ? Is this a bug in exchange 2013 ?
