Hi. Half way through migrating exchange 2010 to exchange 2013.
Have migrated all users mailboxes to new servers and are left with 3 mailboxes in Exchange 2010 EMC that show as "legacy Mailbox" but do not have an associated mail database.
On further inspection of the affected objects (which include the Domain administrator account) I can see in AD Users and computers Attribute editor that the user objects have the attribute msExchHomeSever referencing a long gone Exchange 5.5 Server (i.e. they were not correctly migrated to exchange 2010 from 5.5).
Can I get some advice on either adding a new database on the exchange 2010 server for each object and then migrating object to 2013 or how to remove the old exchange attributes in order that I can then create a mailbox for each and then migrate these over
to 2013
Thanks
