Exchange send as permissions

Hi All,

I recently added a second email domain to our exchange 2010 server and set myself up an email address for the new domain.

Receiving emails works very well.

I used this guide to setup send-as on the Outlook client link.

However I get the the following error when sending from the new email address

You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.

Any suggestions?

I see what your trying to do.  I had to setup another mailbox and add the right to send-as in order to send email.  This of course splits the email up so you would have 1 user with email and another users with email address.

Give the user full access to the mailbox so he can manager both and send from either one.

Thanks for the pointer.

I did a bit of playing around and you set Send As permission for a distribution group, which allows everything to be managed from the mailbox.
