We got a call from a user that just got their laptop upgraded to Windows 10 using Office 2013. When the user tried to create their signature Outlook would freeze. Found a couple of links with suggestions, but this one did the trick.

The trick was to Settings >> Search for Apps. Click on “Apps and Features”, and uninstall “Microsoft Office Desktop Apps” and uninstall it. It did require a reboot, but everything was working after that.

Let us know if this helped you…
