Our client is having exchange 2010 setup. Old ex2003 is completely removed from orgazation almost year back. But now client wants to restore one of mailbox from the 2 years old backup.this mailbox was in ex 2003 and not moved to 2010 during the migration.
So how should i procced with this? I have a backup but with can't restore as no ex2003 setup available anymore in production environment.
Please help me with your suggestion.
