Can't Get Exchange User "Send As" to Work!


By steve - Posted on 17 March 2006

I have a client that wanted to have multiple Exchange 2003 mailboxes appear in the exchange folders list in Outlook 2003 and have email sent by that user from any account appear to have come from that account. In other words, the FROM email address should always be from the mailbox, not from the user and not saying "sent on behalf of".

I found two helpful kb articles from MS 327174 and 291626. 327174 was the most helpful because it told me what I needed. However, I couldn't pick up on why the change didn't seem to matter until I figured it out on my own, then later read the fine print: "To make the setting take effect immediately, stop and then restart the mailbox store."

After following most of the directions, I still got a message saying "You do not have the permission to send the message on behalf of the specified user." I'd check the rights and all my settings, but it still wouldn't work. It was only after I stumbled on restarting the mailbox store service myself that this actually worked. Until you flush the mailbox store cache, it keeps behaving like you don't have the right to send.

While these KB's appear to have applied to specific post-service whah-de-do-da etc., it is still a problem with various Exchange 2003 service packs. It has applied and then didn't and needed hotfixes and then didn't. So, this is still handy stuff to know.

Because Microsoft's KB is not always available, here is the basic information included in each KB:
