"You do not have permission to send the message on behalf of the specified user"

We have a user that currently has a  domain admin accoiunt and has full exchange admin rights in our domain. We are currently running Exchange 2003. This user has 2 accounts. Once is his admin account which is also his domain admin account. His mailbox is linked to the domain admin account. he wants to start loggin into his regular user account and not have to move the mailbox from the domain/exchange admin account to the regular user account.
What happens is when he logs into his regular user account and logs into Outlook he can see the messages, but cannot send them. if he tries to send it, he gets the message:

"You do not have permission to send the message on behalf of the specified user"

We've looked at his send on behlaf of and send from permissions. He just has the send from permission set and it's still not working?

Please help.

Thank you

If his "Regular" account is not a domain admin account but simply a domain user....

Log onto the PC as the Domain Admin
Open outlook
Create a New Outlook Data File or Personal Folder
Move ALL thew email into this personal folder.
Save PST is a location the domain user has access to on the network or any location on the local drive

Close Outlook, Log off

Now log on and the Domain User Account
Open Outlook
From here you can now open the Personal Folder or PST

Now if you want you can move the mail into the mailbox
Or ideally you can move it into a personal folder for his domain user account (this iwll save you from having to have two personal folders open)

Only exception would be, if the PST is nearing its size limit, you dont want to cobine the PSTs but keep them seperate

Thanks so much. this approached work. It's just completely bizarre why this extra step had to be done. Was it a security feature in Outlook 2010? We're going to be upgrading to Exchange 2010 pretty soon so maybe we won't have to deal with this in the future. Thank you for the tip.
Most likely there is an attribute in AD that Outlook 2010 is looking to see that does not exist in Exchange 2003.  With Microsoft products I am always grateful when the problem is fixed and I am not always interested in finding out why!
