I'm not sure if the built-in management roles can accomplish what I want.
We are going to move mails from a GroupWise server to Exchange 2013 using the application "Kernel" - and for this I need a user having full access with no restrictions on all the Exchange server. I understand that Domain Admins are having Deny ACE on Exchange servers. What will the best approach be to grant a specific user full and non-restricted access to all mailboxes on all Exchange servers? Any Built-in Groups that can take care of this? I guess Help Desk will not be enough.
Regards, Lars.
