I have a user who has left the business and had a mailbox, we need to delete the AD account but retain the mailbox, can this be achieved in Exchange 2010?
Is there way to assign full ownership of the mailbox to another AD account either by sharing the mailbox or keeping it as a regular user mailbox so we can delete the original AD account linked to the mailbox.
We have attempted to share the mailbox and assign ownership to a different AD user but outlook won’t allow to attach the shared mailbox.
We need to retain the mailbox in exchange so it can be accessed if needed. We are not willing to export as PST due PSTs get corrupt.

Thank you for your expert advice.
