  2. Click File.
  3. Click Options.
  4. Click Trust Center, and then click Trust Center Settings.

  6. Click Restore Defaults or manually deselect the “Open” and “Save” checkboxes for; Web Pages, RTF Files, Plain Text Files.
  7. Click OK.

If you get this pop-up error, "You are attempting to save a file type (RTF Files) that has been blocked by your File Block settings in the Trust Center" when creating a new or editing an existing Microsoft Outlook signature, the step-by-step directions will need to be followed.

The instructions provided, following the error, will not resolve the issue from within Microsoft Outlook. The Signature Editor is based on Microsoft Word and that is the application producing the error.
