Part 1: Common Causes for the Outlook Signature Not Working

Even though there is no logical explanation for the Outlook signature function not operating, certain issues can be blamed. Some of the causes of the signature not working in outlook 365 are as follows:

Issue 1: An issue with Language ID

Users may encounter a similar problem when they pick the Stationery and Fonts option in Outlook. These problems were discovered and limited to Office users with the Language ID="en-gb."

Issue 2: Pre-installed Microsoft Office desktop apps

Another possibility is that you installed an Office subscription on a PC that already has installed Microsoft Office desktop programs.

Issue 3: Wrong Registry

The signature button may be inactive owing to a registry mistake pointing to the wrong location of Outlook.exe.

Issue 4: The Signature button is disabled by Group Policy

Your business may have configured the signature in its way and disabled the Signature option at times. Employees will be unable to modify the signature format in this manner.

Issue 5: Code Issue With the New Update

Problems with the signature function are most commonly encountered while updating earlier versions of Office. When the outlook signature fails to function properly, error log entries arise. In such cases, try updating or installing a newer version of Microsoft Office.

Issue 6: Unable to Read HTML Format

If the signature is in HTML format, the recipient may not see it in HTML format, especially if they view the email on their phone. Because certain phones can only read plain text, so the signature may not display on the receiver's device even if delivered.

You must have at least Exchange 2007 installed to see your email in HTML format. However, this is different with picture signatures.

There are numerous ways to address if Outlook freezes when opening signature, depending on what is causing it. There may be some upgrades necessary or a registry key change; try one of these remedies based on the likely causes of the problem.

Some of these options, such as altering the registry key, may cause changes to your PC settings and possibly data loss. As a result, always backup your data before making any changes.

Step 1: Log in to your Outlook account through the web.

Step 2: Select View All Outlook Settings from the Settings menu.
