Dear Experts, <br />
<br />
If user id has already been added in the mailbox and we accidentally deleted the user id in Active directory, will it be automatically mapped to the user's mailbox if we create the same user id in active directory again? I know each id has an unique security idenifier but i m not too sure on the Exchange Server's aspect. I actually deleted the same old user id and added the new id again, therefore not sure if this is the right step. Please advise.

Dear Experts,

Is recreation of id needed in Exch Srvr if deleted and added again in Active Dir?
