Using Send As in Outlook 2003

Posted on 2008-10-08
Last Modified: 2012-05-05
One user wishes to send mail via Outlook 2003/Exchange 2003 as someone else (Send As in Outlook).  This someone else is an alias in her AD profile (no real user account in our AD).  When she attempts this, she gets the "You do not have the permission to send the message on behalf of the specified user".  I've looked over other articles and see that it's necessary to grant that person Send As permission (for "This object only") and went as far as restarting the mail store on Exchange without any success.  What haven't I done that's required?

Thank you.

you need to set up a second account - the second account should be pop/smtp with the internal ip address and AD username and password - and the alias email address you want to use.
Then you can configure outlook not to receive mail for this account (in define send/receive groups)
then when you create an email you will have a new button on the toolbar for account.
You will also be able to define a second signature that will change automatically.

to clarify - that is a second account in outlook - not a second AD account, or a second profile.

send as - is only to send as another AD user that has given you permission to send on their behalf - eg a manager/secretary - not for the purpose of sending as the alias.

Thank you for the prompt response and clairification.  My understanding now is that when I use that second account, it will automatically appear to be coming from my alias.  However, when I did as you said, and send an email using that account, I'm getting an email back from the system stating: "Unable to relay for xxxx" where xxxx is the external recipient I'm trying to reach. What's up with that?

your exchange server will need to be configured to allow an authenticated user to send mail - check the username and password you used - did you do the test button on the account setup?
