I have created a mailbox that needs to have people be able to "Send As" that email address.  This is working from OWA, but it won't work with Outlook.

I'm using Outlook 2007 with Exchange 2010.

I have tried adding them to the "Send on behalf" list from the EMC, and have tried adding them to the "Send As" list from the EMC as well.  Both methods give the same result.

In my research, I discovered that OAB files might need to be updated so I downloaded the Address book from Outlook and even deleted the OAB files from the profile.  Nothing has worked.  I have also tried running Outlook with Cache mode off...no dice.

The fact that it works from OWA and not Outlook tells me that something is up with Outlook.

This is crazy and I just can't figure out why it's not working.
