Outlook Web App: Attachments may only be viewed as a Web page

February 11, 2012 · by dave.webb · in Outlook Web App, Security, Troubleshooting

Since upgrading to Exchange 2010 users regularly rep0rt that they are unable to open attachments when using Outlook Web App. They all receive the same message:

For security reasons, this attachment may only be viewed as a Web page. It cannot be saved to disk.

It didn’t take long to resolve this one and it was quite a simple fix: when logging in, be sure to select Private Computer instead of Public Computer.

This relaxes the security settings and allows users to open attachments.

Does not work for me – we have a 2 step entry the first from a special 6 digit number generated by outlook – still have only the web page option to open which seems fixed as the email is received. I have a remote computer tying into Outlook
