Hi!
We are migrating from Ex2010 to 2013. We have moved Microsoft Exchange mailbox to Ex2013. There are some other mailboxes like
SystemMailbox{1f05a927...
FederatedEmail.4c1f4d8...
Which are shown when we type Get-Mailbox -Arbitration
Should we also move them to EX2013 and by creating a move request from ecp?
Thanks.
