Outlook 2000/98: could not open one or more attachments

When a message with an attachment is saved to a personal folder and then later I try to forward it, I receive the message "could not open one or more attachments".  When click ok, message opens to forward but attachment is stripped.  If I forward the message from the inbox, I do not get this message.  I have several users with this issue running Outlook 2000 or Outlook 98.
Also if the message is successfully forwarded, then the recipient receives the message and the attachment is stripped.  Tried security updates and service packs for Office on the workstation.
Using Exchange 5.5 on server.

Blocking potentially dangerous attachements is a function of Outlook security settings.  The following article explains how it works, what file types are blocked and tells you how to get the blocked attachments.  Go to:

Problem is not with blocked files.  This was working last week and now does not.  I tried most of the security settings in the articles already and none worked.
Can forward from inbox but not the pst.

You might also try compacting your PST:

What happens if you create a new Outlook profile - does the problem follow?

I've seen this before with 5.5

Antivirus software enabled?  Upgraded etc since last week?

ran scanpst and found not problems.  No help with issue.  Can create a new PSt and same problem so PST size is not involved. I created new profile on my laptop and problem follows.  Desktop has Ol98 and laptop OL2000.  Also same issue on multiple users.  I have over 200 users and only a few try to forward in this manner so i have not heard from most of them yet.
I have Norton Antivirus on the desktop and definitions can be updated daily from another server.  I have Trend ServerProtect on an Exchange cluster running Exchange 5.5.  The definitions I assume are also updated daily if not hourly.  I would have to check with the network guy on this to be sure.  I have another location in NY with separate servers that do not have this issue so far.

You may want to temporarily disable email scanning and see if you can forward from another folder than the Inbox to troubleshoot.  Also temp disable NAV completely to test.

I stopped and restarted the Trend ServerProtect and this solved the problem for now.  My network team is looking into this issue.
Thanks all for the comments
