Hello,
I am in the process of decommissioning my Exchange 2010 server from Production, all mailboxes and public folders have been moved to Exchange 2013.
I have a few questions that relate to the decommissioning process.
I've migrated all user mailboxes to 2013, but in Exchange 2010 MMC GUI I see all the migrated users in the "Recipient Configuration > Disconnected Mailbox". This is due to exchange retaining mailboxes for a certain time before removing them, should I force remove all these disconnected mailboxes before I remove all databases and uninstall Exchange 2010?
There are a few mailboxes left that I don't know what to do with, these are
Name Alias ServerName
---- ----- ----------
SystemMailbox{1f05a927... SystemMailbox{1f0... xxx-mail
FederatedEmail.4c1f4d8... FederatedEmail.4c... xxx-mail
SystemMailbox{e0dc1c29... SystemMailbox{e0d... xxx-mail
SystemMailbox{bb558c35... SystemMailbox{bb5... xxx-mail01
Migration.8f3e7716-201... Migration.8f3e771... xxx-mail01
My Exchange 2010 is "xxx-mail" and my Exchange 2013 is "xxx-mail01", what do I do with the SystemMailbox and FederatedEmail mailboxes on Exchange 2010? Are these safe to remove? What is their purpose?
Thanks for your help
