Exchange server 2003 running on small biz server, outlook 2003 clients.
If I create a meeting request and invite, say, 4 internal (exchange server) users, they all receive the invitation 'as expected' - they get a message that has 'accept'/'decline'/'propose new time' options, etc.
But if I create the exact same meeting request, but invite a 5th person, and that 5th person is an external user (eg, a user at email@example.com, etc - then all 4 internal recipients now receive a more standard email message that still references the meeting, but is no longer a meeting invitation and no longer has the 'accept', 'decline', etc options.
Ironically, the one external user DOES get the message as an invite (assuming they are using outlook as their client).
Can tnis be changed so that, regardless of whether we have external recipients or not, the internal folks get a proper invite? We are in the habit of inviting a mixture of internal and external people constantly, and we will never know who these external people are ahead of time (so they can't be configured as 'contacts', if that's part of some possible solution).
