Sometimes, when you select the Signatures button, Outlook hangs or closes, and users are not able to add a signature. Read on to know the possible causes of this error and also some solutions to fix the issue if the Signature button is not working in Outlook.

What causes the Signature button to freeze?

Here is a list of common issues that are causing the Signature button in Outlook to freeze.

• An issue with Language ID: Users may face a similar issue even when selecting the Stationery and Fonts button in Outlook. Both these issues were found and were isolated to Office users with Language ID=”en-gb”.
• Pre-installed Microsoft Office desktop apps: Another reason could be that you have installed an Office subscription on a PC that has pre-installed Microsoft Office desktop apps.
• Wrong Registry: The signature button may be frozen because a registry entry is pointing to the wrong location of Outlook.exe.
• The Signature button is disabled by Group Policy: Sometimes, your organization may have set up the signature in their own way and disabled the Signature button. This way, employees won’t be able to make any changes to the signature format.

Depending on what is causing the issue of the frozen Signature button, there are several ways to resolve this problem. There may be some updates required, or maybe a change in the registry key; try one of these solutions based on the possible reasons behind the problem.

Some of these solutions, such as changing the registry key may change your PC setting and you may even lose some data. Hence, always take a backup of your data first and then make the changes.
