Are you saying this only happens -- and I'll assume you have replicated it
in different circumstances -- with Outlook 07, or only with RPC>HTTP, or
only with both?

Subject: Outlook 2007 on Exchange 2003 SP2, Calendar Update, Mail Queue
Problem.
I have an odd problem which I believe is being caused by Outlook 2007.
My scenario:
Exchange 2003 Ent SP2 Win2k3 Ent SP2 (Exchange is both Front/Back End,
RPC HTTPS, Active sync, OWA, all in wonder box etc.)
Outlook 2003 & 2007 Clients
A remote user from home connected via RPC over HTTPS with
Outlook 2007 will create a calendar Invite and sent it off to a bunch of
people, some recipients are internal and some are external. That email
will go through fine. However if that Outlook 2007 user modifies that
Calendar invite by proposing a new location or time etc, and then sends
it off it will get stuck in my Exchange 2003 servers mail queue. This
also sporadic and does not happen every time, at least once or twice a
day though. Basically the email will sit in queue forever until and NDR
is created 2 days later. Looking at the queue for the email Exchange
says, "Unable to open message for delivery"
I have not seen this with any Outlook 2003 users.
So far I have found a few articles describing a similar problem but no
clear cut solution.

Today I turned on SMTP Tarpiting, to see if it makes any difference. I
don't believe this will fix the issue.
I am reluctant to install the hotfix from the article 938650, because
Microsoft doesn't quite explain the problem the same, and they haven't
approved or really tested the hotfix yet.
Thank You,
