Hi All,
I recently added an Exchange Admin group to one of my mail databses using the Get-MailboxDatabase -identity “maildatabase” | Add-ADPermission -user ExchangeAdmins -AccessRights GenericAll cmd. I then manually removed this from a mailbox in the datbase via EMC, which has messed up all permissions on the mailbox. The mailbox has had all permissions re-assigned to it, I recreated owner rights etc but the user still can not access the mailbox, either thru OWA or Outlook. Both return a permissions error. I have also disconnected and re-connected the mailbox via EMC but no go. I moved the maibox from one db to another with default permissions still nothing. Everything looks right but it's not allowing anyone to access the mailbox. For the time being I have set up a forward on the mail account so mail is being delivered to a temp box.
How can I re-assign default 2010 permissions to the mailbox and is this the way to go? I don't want to recreate the mailbox unless absolutly neccesary.
Thanks for any pointers.
