This is a strange request and one that I honestly pushed back on but management is pushing back harder so hopefully there is a quick and safe solution to this question.
We have an Exchange 2010 HA setup with 2008 R2 domain controllers. We have a home grown app that sends out mails to interal users. In the past I just gave the service account the "Send As" permission from the Exchange server and everything went off ok. Now the developers came back and they want to do it for over 200 accounts.
Is there a cmdlet or GUI way to give this one service account "Send As" permissions to multiple mailboxes...instead of doing them one by one?
Thanks in advance.
