Exchange and Outlook problem with attachements

[Rovin]

Chaps, we have a problem when replying or forwarding on a message that either contains or has an attachement, the attachement does not get through to the recipeint. Now, we have several exchange servers in the organisation all with site connectors and replication working OK. This problem was first seen a couple of days ago internally - but after checking all services, disk space etc, we cannot see any problems.

The clients are running a mix of Outlook 97, 98 or 2000 and we only seem to get the error indescrimantely, which doesn't help matters. Anyone got any ideas? We don't have mailbox restrictions in place either.

Thanks.

What is in the attachment? Exe files? Also, what kind of Antivirus are you running on the Exchange Server and clients?

First, the mail servers have been working fine. And we haven't made any changes to any of them for 4 months, other than general mailbox management.

Anti-virus wise, we use external service from Messagelabs for all inbound and outbound SMTP. At the client end we run a mix of Norton and Norman Data Defense. The servers run the same, all without problems or errors, nothing is showing in the event viewers either.

The attachements can be anything, from .doc, .xls to zip and exe's. It appears to be the whole attachement that we have the problem with and not specific to any one type.

Also, the problem is only happening to a certain number of users, which makes no sense at all.

Have and Outlook Security packs been install on clients. MS has screwed around with those extensions of SR-1 so much it is very hard to figure out which one(s) are right for a desried implementation. One or more of them has the ability to "secure" Outlook in such a way that attachments are not visible.

In Outlook on an affected user's PC, go to Tools - Options - Security tab and click the Attachment Security button (if there is one - some patches change the security settings and remove that button).

All instances are installed with office 97 to SR2b, but Outlook is upraded to 98. Just checked on one PC and the only option in the security tab for attachments is the action to be perform on inbound messages, which is set to high (default). Nothing else seems to be present, I will have a go at installing the latest patches for outlook and check if any else is available in the security options.

Thanks.
