I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

First a shared mailbox is a normal mailbox associated with a disabled AD user object. A user mailbox is a normal mailbox associated with an  enabled AD user object.

If you convert a user mailbox to a shared mailbox the only thing that happens is the AD user object becomes disabled but the mailbox, permissions and content remains the same, so basically the only difference in essence is the status of the AD user object associated with the mailbox, one is a disabled object (shared), and the other is an enabled object (normal). If you convert a user mailbox to a shared mailbox all user with full access to that mailbox retains that access.
