Exchange Server 2010 – Grant Full Access Rights for All Mailboxes

This will grant full access rights to all mailboxes for the Domain Admins group. Obviously, you need to replace “YourDomainHere” with your actual domain name. Type the following inside of the Exchange Management Shell:

Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'UserMailbox') -and (Alias -ne 'Admin')} | Add-MailboxPermission -User "YourDomainHere\Domain Admins" -AccessRights fullaccess -InheritanceType all
