Outlook 2010 Tips: Disable Attachment Preview

Microsoft Outlook 2010 has a feature that allows you to preview the attachments and documents if the handler is available for that particular file type. This feature may not be of any use to many users, since it can slow down the process of viewing an email(only if you have a low to medium-end computer).

To disable Outlook attachment preview, click the Office(File Menu) button and choose Options.

  1. AWESOME, thanks!
    If this didn’t work for you, close & restart Outlook…I had to do that for the change to take effect.

  2. 3 years an no one noticed that all comments are about the mail preview (which can easily be switched by a button)? This article is about the preview of attachments (like pdf, word, etc), which is a totally different thing.

  3. Did not work…but I figured it out. Simply click View Settings (Under View Tab), then click Other Settings, then simply select No Auto Preview (in the center of the page). Viola…no more previews!
