If you are not affected by this Microsoft 365 bug, then, in most cases, the issue is caused by a Registry entry pointing to the wrong location of Outlook.exe.

That will first remove this pre-installed software as you won’t need it when you already have Microsoft 365 installed.Īnother way to go would be to uninstall the “Microsoft Office Desktop Apps” application from your computer yourself.įor more info, also see: Outlook freezes clicking the Signature button Method 1: Registry CLSID GUID modifications If you are still running into this issue, make sure you use a newer installer for Microsoft 365 (for instance by downloading it by logging on to instead of using an old installer from your Downloads folder). I’m mentioning this first because the solution to that issue is much simpler to fix.Īt one time, new computers often came pre-installed with the “Microsoft Office Desktop Apps” application which is incompatible with Microsoft 365 Version 1801 and earlier. In rare cases, the Signatures… and Stationery and Fonts… buttons in Outlook's Options may not be working for you.Ī variant of this issue is where Outlook freezes when you press the Signatures… button. Luckily, there are a few ways to reinstate the "Signatures…" and "Stationery and Fonts…" features again or use a simple workaround to still edit your Signatures. Another instance where this might happen is when you have a security suite or virus scanner installed which was a bit overly active with protecting the Registry during your installation of Office. It happens most often when a newer version of Office was removed (like for instance a trial) and an older version was installed and then later updated again to the newer version but also going from 32-bit Office to 64-bit Office or vice versa.

This can happen in rare cases but with an application used by so many, even rare cases affect a lot of people. How can I get my Signature Editor to work again? I tried repairing my installation of Office but that didn’t work. The same is true for the Stationery and Fonts… button. When I wanted to edit my Signature, I noticed that the Signatures button isn’t working at all when I click on it.
