[Urgent]Accidently disabled shared mailbox (multiple users)

I am a beginner and accidently run "Remove-Mailbox..." instead of "Set-Mailbox..." while modifying user's access to a shared mailbox. Now I want to know, since multiple users had access to the shared mailbox, do we need to provide access to every user on the shared mailbox again, after reconnecting the shared mailbox to the account ?

I am working on exchange server 2010.

Thanks in advance..
