A number of our users have Full Access control of multiple mailboxes in Exchange. These users also have the additional mailbox white-listed in BMA.
For example: Tim.Smith@company.com has Accounts.Payable@company.com added to his BMA white-list. He can search AP using the BMA Web GUI search feature but not the Outlook BMA Search Plugin. It would be incredibly helpful to our users if they could also search their white-listed mailboxes using the Outlook BMA Search Plugin.
