Nasty Co-existence Issue Exchange and Groupwise

[GregE240]

Can someone help with this?

Got a customer who is migrating from Groupwise - Exchange.

In order to speed things up, it is been suggested that the Groupwise distribution lists be recreated in Exchange. This means that they will contain (during co-existence) both Groupwise and Exchange contact details. Synched the new group over via the Connector.

So we've set a test group up, as per the above. From Exchange (well, Outlook), no worries, the message goes to both Exchange and Groupwise recipients, but from Groupwise, the message goes to Exchange users okay, but we are seeing non-deliverable messages for the Groupwise users?

Any ideas? I think the problem lies at the Exchange end...but theres not much to configure.

Cheers,
Greg

First thought, got any headers to see which server is rejecting it? (Tricky to tell from the post)

I'm just off out of the office, but if no-one replies, bump the thread tomorrow or mail me through the profile and I'll see if I can assist.

A bit of background on the connectors and Ex/GW versions might be useful...

Oh, and turn diagnostic logging up to the max on all the connectors in Ex and trowel through the event log, that might tell you what you need to know.

OK, header is as follows:

Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:

POST OFFICE LOCATION.POST OFFICE NAME.DIST_GROUP 5/19/2005 15:01:00

It seems like the message is going from Groupwise - Exchange okay (because the Exchange members of the group receive the mail okay). From there I'd have thought Exchange would see there are two GW users in the group, and send the messages back over the Connector to be resolved by Groupwise. It seems Groupwise is having trouble with this?

Thanks in advance for any help.

Although it relates to Notes it looks suspiciously like the culprit. Can you adapt that solution to the groupwise connector?

Thanks, will have a look at the .ini file and see what can be done.
