I have a colleague who is using OWA instead of Outlook. she can't open an attachment called securedoc.html from the bank. I can open that file through Outlook. But while I am using OWA, I can't open it either. I tried to forward to my gmail or hotmail, I can open that file through IE successfully. While I download that file through OWA, the size becomes smaller (12 KB) instead of the original size (106KB). We are using Exchange2007. I changed some settings in Exchange about the attachment allows. Still can't open the attachment successfully! Please help me!! Thanks!!

Sounds like the "Safe HTML" feature kicking in: You may have to figure out a different way of sending it( zipped? ) or have her use Outlook Anywhere if remote. http://support.microsoft.com/kb/899394 http://www.windowssecrets.com/2008/06/05/03-Outlook-Web-Access-corrupts-HTML-attachments http://www.windowsitpro.com/article/email/safehtml-friend-or-foe-.aspx
