How to Manage Previewers in Outlook 2010

If you are unable to preview Word, Excel and PowerPoint files in Outlook 2010, make sure that the previewers are not disabled. The attachment previewers are enabled by default. Here's how the previewers work in Outlook 2010. First of all, make sure that the attached file that you are trying to preview in Outlook has the application installed. In other words, if you are trying to preview a Word file in an Outlook message then Microsoft Word must be installed on your computer. For security reasons, you have the option to selectively remove some or all the attachment previewers. If you want to selectively use only certain attachment previewers in Outlook then follow these steps.

1. Click the File tab.
2. Click Options
3. Click Trust Center.
4. Under Microsoft Outlook Trust Center, click Trust Center Settings, and then click Attachment Handling.
5. Do one of the following:
   • To turn off all attachment previewers, click Turn off Attachment Preview.
   • To turn off a specific attachment previewer, click Attachment and Document Previewers, clear the check box for a previewer that you want to turn off, and then click OK.
