Hi guys, a customer of ours have a strange problem that has got me really frustrated.
We have a plain Exchange 2003 SP2 with OWA form-based with a self-signed certificate. OWA is published to the outside through an ISA2004SP2.
When trying to open zipped attachment from the local network (not through ISA), the users get the following message: "The Compressed (zipped) Folder is invalid or corrupted." If the user choose to right-click and save as, the file gets downloaded just fine.
When external users (through a mail server publishing rule, see http://www.mcse.ms/archive99-2005-5-1473074.html) tries to open a zip-attachment, they receive a "Error Code: 500 Internal Server Error. Not implemented (-2147467263)".
I believe these problems are related, so I am currently concentrating on fixing access to zip-attachments from the local network first, and then hope the 2147467263-problem also gets fixed.
I found the following hotfix at support.microsoft.com: http://support.microsoft.com/?kbid=875525
"When you use the Outlook Web Access client to open a compressed (.zip) file attachment that you downloaded from an Exchange Server 2003 computer, the file is corrupted".
I've tried all possible compression methods, both none, low and high, to no avail.
I called MS, but they did not suggest applying this hotfix as this was one of the hotfixes included in E2003SP2.
http://support.microsoft.com/?kbid=906669&SD=tech
I can see no relevant events in the application-log, even with diagnostic logging set to the max.
I believe this might have something to do with gzip-compression. I've looked all through System Manager, but I can see nothing refering to gzip.
Please help me with this one, and I'll buy you a beer :)
Cheers, Rolf

I managed to solve the first problem by clearing the "Do not save encrypted pages to a disk" from IE -> Internet options -> advanced -> settings -> security.
Now only the "Error Code: 500 Internal Server Error. Not implemented (-2147467263)"-problem through ISA2004SP2 persists...

It's me talking to myself again..
The second problem (Error Code: 500 Internal Server Error. Not implemented (-2147467263) when opening zip-attachments in OWA published through a mail server publishing rule in ISA2004), was indeed caused by a combination of bugs in SBS2003 Premium and another bug in ISA2004 (even with SP2).
First thing first: The CEICW-wizard in SBS2003 does not create the right type of publishing rule. The solution to this is to delete this rule and manually add a Mail server publishing rule to publish OWA.
On top of that, even when using a mail server publishing rule to publish OWA, a bug in the ISA2004SP2 compression filter causes the "Accept-Encoding: gzip" header never to reach the client.
Thanks to MS PSS for helping sorting things out. I suspect a KB on this issue out soon...
