OWA 500 error when clicking on URLs

[davidinark]

I have ISA 2006 and Exchange 2003 on Server 2003 (two different boxes). When my OWA users click on a URL, they get a 500 server error pointing them to a Security filter.

I checked out the closest thing I found was regarding KB837865 (checking to make sure the high bit option is unchecked). I looked at all of our rules and anywhere there was an HTTP setting, I made sure the high bit was unchecked. As it turns out, none of our HTTP-enabled rules had the item checked.

I have looked and looked and cannot find a solution to this. Where else can I look?

A sample link is:

I know the problem seems centered around the %2520, but I can't seem to find the place to fix this.

All my client machines are XP with SP2 or SP3 - makes no difference in result.

Any ideas?

Well, I'll answer my own issue in case anyone else has the same problem. The problem? Change in System Admins. Ours left this summer and I was given the task, learning ISA as I go along.

We had a web rule that I overlooked during my first run-through. Call it 'operator headspace' or a PICNIC, either way it was all about the guy sitting in the driver's seat. Figures.
