One of our clients needs all users with a mailbox to be granted Full Access
and Send on Behalf
permissions to another shared mailbox.
The easiest way to do this would be to give a security group the needed permissions, but Exchange 2013 is only allowing delegates that are users. I've tried via ECP and the following (assuming "sharedemail" is the shared mailbox and "AllUsersSecGroup" is an AD Security Group):
Set-Mailbox -Identity "sharedemail" -GrantSendOnBehalfTo "AllUsersSecGroup"
I can't use Add-MailboxPermission
because there's no operator for Group
instead of User
.
