Exchange 2003 meetings to clients on Exchange 2007

[Guest]

Recently we began seeing an increase in Delay and Failure notices in
relationship to meeting requests with outside persons. Specifically, if we
include someone that resides on an Exchange 2007 server (outside) the meeting
will surely generate a delay then subsequent failure.

If the user on the Exchange 2007 server creates the meeting, we get it just
fine. If we then try to edit the meeting; new time, new people or resources,
the request will not get back to the originator and we will receive a
delay/failure.

Now, if we send a meeting to someone on an Exchange 2003 box, no problems.

Us:

Exchange 2003 SP2
Windows 2003 SP1
Outlook 2007
Outlook 2003 SP1 & SP2

Them:
Exchange 2007
Windows 2003 SP2
Outlook 2007
Outlook 2003 SP2

Tried:
Disable Spam filters
Disable AV
Routine Exchange DB Maintenance

Message in Exchange Queue
"Unable to open message for delivery"

Message in NDR
"Could not deliver in the time specified"

Any Ideas?

No resolution yet.

We are finding the same thing you are. Which is that not all requests get
held up. We have also found that the problem seels pretty random. The only
thing we have narrowed down thus is that if you send a meeting to someone at
Microsoft.com or w-link.com you will most likely get this issue.

I will keep you posted if I hear anything.
