Having trouble with Send As permissions in Exchange 2010 (SBS 2011)

Posted on 2014-03-03
Last Modified: 2014-03-03
Hi, we have an SBS 2011 server. I have granted USER A Send As permissions to USER B's email. I Have verified permisisons in the Exchange console and from the Exchange Management Shell.

When USER A selects USER B in a new message form in the FROM field and sends a message, it is returned as undeliverable due to the user not having Send As rights.

Please test this functionality in OWA and let me know if the same issue occurs or if the user is able to use sendas through OWA.

This will help me with the next troubleshooting step.

How long ago did you grant this permission?  It can take a couple of hours to take effect due to Mailbox Cache Idle limit.

Or, to prevent someone jumping the gun on a solution..  If OWA functionality works with sendas, you can simply:

Create a new email message
Click the from then choose other email address
Click From and then choose Global Address List (may have been another list which permissions would not propagate through)
Now choose the user to send as

That should work

It is taking quite long time from setting the Send-as to get it effective... Stay calm :-)


Please try to delete the recipient from cache, when you entering the from field...

And enter the from item manuály or from the address book
