SYMPTOMS

If you attempt to forward a meeting request while using Outlook (IMO), you may receive the following error message:

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

CAUSE

This problem occurs if an Outlook Corporate or Workgroup (CW) user sends a meeting request to an Outlook Internet Mail Only (IMO) user, and then the IMO user attempts to forward the meeting request to another e-mail address. The server will only grant "send-on-behalf-of" permission for other Microsoft Exchange users, not one-off addresses.

This problem does not occur when an Outlook (CW) user forwards a meeting request. It also does not occur if an Outlook (IMO) user forwards a meeting request from another IMO user.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
