How to Turn Off the Attachment Previewer in Outlook 2013

If you have Outlook 2013 set up to use the Preview panel, then you have probably noticed that you can view a preview of an attachment by clicking on the attachment once.

This allows you to view the contents of the attachment if the previewer for that attachment is installed on your computer. For Microsoft Office files, you can often even copy some of the data from the Preview.

But if you prefer to work with attachments in their native programs, where you have access to all of the features of the program, then this Preview mode can be more of a nuisance than a help. Fortunately it is a feature that you can turn off in Outlook 2013 by following the steps in our guide below.

The steps below are specifically written for Microsoft Outlook 2013, but these steps are very similar for Microsoft Outlook 2010.

Step 1: Open Outlook 2013.

Step 2: Click the File tab at the top-left corner of the window.

Step 7b: If you would prefer to only turn off previews for certain types of attachments, then do not check the Turn off Attachment Preview button, and instead click the Attachment and Document Previewers button.

You can then clear the check mark to the left of each file type that you do not want to preview. For example, I have chosen not to show previews of Excel files. Click the OK button when you are done customizing your attachment preview options.

Step 8: Click the OK button on each of the open windows to save your changes.

You will then need to close Outlook and restart it for the attachment previewer feature to be turned off.

Would you like for Microsoft Outlook 2013 to stop asking you if you forgot to include an attachment? This guide will show you how to disable that setting. You can also follow those steps if you would like Outlook to start reminding you about attachments.
