I have many mailboxes on Exchange 2010 SP2. (I also have many more on Exchange 2003 and am in the process of migrating those)
In Exchange 2010 I've granted Full Access permissions to our Mail Admin group using the following PS:
Get-MailboxDatabase | Add-ADPermission -User "Email Admins DL" -AccessRights GenericAll -inherited
I can see this group under Full Access permissions, but the accounts in that group still don't have access.
If I add the accounts to a mailbox individually, not as a group, the permissions apply correctly.
