OWA upload attachment 404 error RRS feed

  • Question

  • I have set all size limits in Exchange to 100mb. I attempted to use OWA (exchange 2007 on SBS08) to send a file size 39.1mb and got "404 error - file or directory not found" while uploading the file to the message from the desktop. I was able to upload 3 different files all sized over 10mb, total size was about 35mb, and that sent fine. How or what do I need to adjust to be able to upload a single file that large? Is is a timeout issue? Any help is greaty appreciated as I am at a loss after days of forum searching to solve the issue.

    Thank you in advance!
