Outlook freezes clicking the Signature button

Last Updated: August 14, 2018


When you click the Signature button, Outlook hangs and you are not able to add a signature.

This issue occurs if you install an Office subscription on a PC that has pre-installed Microsoft Office desktop apps.

Note: This issue is fixed in Office Version 1802 (Build 9029.2167) or higher. When you install an Office Subscription with that build or higher, it will automatically remove the pre-installed Microsoft Office Desktop apps.


To workaround this issue, uninstall the pre-installed Microsoft Office Desktop Apps:

  1. Right click the Windows Start button and click Settings.

  2. Click Apps, and then click Apps and Features.

  3. Choose Microsoft Office Desktop Apps and click Uninstall.
