OWA 2003 Attachments Problem

[DaveDundeeUK]

Hi Everyone,

I'm having a problem downloading attachments from OWA 2003 external only (SSL Enabled). Downloading attachments internally works perfectly. Whenever I right-click to download an attachment, no matter what attachment it is or which ever user tries, it displays the error:

----------------
Internet Explorer cannot download file.pdf?attach=1 from "server address"

Internet Explorer was not able to open this internet site. The requested site is either unavailable or cannot be found. Please try again later.
------------------

I've used a pdf file in the above example but it is same problem with any file type. Could it be something to do with the "?attach=1" after the attachment name?

I was also having a problem displaying some e-mails but disabling URLScan in ISA 2000 fixed that.

Does anyone have any suggestions?

Thanks in advance

Dave
