We decommissioned & removed our BES over 3 years ago when we were still running Exchange 2007. We migrated to Exch 2013 a year ago, but I left the BESAdmin account out there. The BESAdmin account has been disabled for a year, but is still listed under Full Access on all mailboxes.What is the safest way to remove this account? My plan is to run the command below to remove the account from all mailboxes & then delete the user account.
Get-Mailbox -ResultSize Unlimited | Remove-MailboxPermission -AccessRights FullAccess -User "domain\besadmin"
Any other thoughts/suggestions?
Thx
