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
To workaround this issue, uninstall the pre-installed Microsoft Office Desktop Apps:
- Right click the Windows Start button and click Settings.
- Click Apps, and then click Apps and Features.
- Choose Microsoft Office Desktop Apps and click Uninstall.
Restart the computer, and then install the office suite that you have license.
Good luck my friend, if you need more information, please leave the comment in below. I am Aji’s dad, see you later.
