Hi we had an issue and needed to created another exchange server on our domain. We migrated all the mailbox and everything is working OK. Now we are trying to uninstall exchange from the original server but we are getting having an issue. For some reason on of the databases still have 3 mailbox in them. 2 of them are system mailboxs and 1 is a federated mailbox. We tried to copy them to the new server with no luck.My question is can i just delete them or is there something i need to do for this mailbox's
Thanks
