Outlook 2010 opens up a "file download" window with every email

It is not a feature of Office 2010. Open Control Panel -> Programs and Features -> Microsoft Office 2010 and select Change. Do an office repair. See if that helps, and let us know. ... Thinkpads_User

Thank you for your help. I did the Office repair but unfortunatley that did not do the trick. I am still getting the window pop-up pages everytime I open an email.

Please remove any signatures and themes you are using. I think you might find an object in either of them that triggers this file download dialog.

Thanks for the suggestion. I do not have any signatures and restored the default settings to outlook. The window that pops up each time I try to open an email says "temporary folder". It downloads quickly then another window pops up. In this window there seems to be links to everything that the sender has ever sent me. Hopefully I'm explaining a little better what is happening so my issue can be figured out. Thanks!

Consider doing a complete uninstall of Office 2010, restart and full (not typical) reinstall. If that doesn't work, then perhaps one of your incoming emails was infected with a virus. ... Thinkpads_User

Thanks. I will try that. Hopefully it will work. :)

I did a complete uninstall of Office 2010 and full reinstall and my problem still exists. My outlook at one point became frozen so when I restarted it started in safe mode. The problem of the "temp file download" windows popping up--vanished--until I restarted and the problem was back when not in safe mode. I am very confused.

That was it! I disabled all the add-ins. Problem solved. I can't thank you enough!

Very helpful. Easy to understand. Thank you!
