DGS - MS Outlook ( Intermediate ) - Solving the Signature or Stationery and Fonts button doesn't Work



After installing Outlook's January 2018 update, some users are unable to edit signatures.

Microsoft has identified the cause as having both the Windows app store version installed as well as a "normal" version. This would be the case if you have a new computer and Office was preinstalled, then you installed your own copy of Office.


Method 1 : Uninstall Microsoft Office Desktop Apps

  1. Open Settings, Find Apps & features.
  2. Click on the Office Desktop App and select Uninstall
    uninstall the office app
  3. A second small Uninstall dialog will open, for you to confirm.
    confirm uninstall office app



Method 2 : Uninstall Apps Package with Powershell

If you prefer using PowerShell, follow these steps:

Open PowerShell in run as admin mode then paste:

Get-AppxProvisionedPackage -Online | where-object {$_.packagename –like "*Outlook*"} | Remove-AppxProvisionedPackage -Online


Then input below command : 

Get-AppxPackage "*Outlook*" | Remove-AppxPackage


Close the PowerShell window and open it without using run as admin. Run this command:

Get-AppxPackage "*Outlook*" | Remove-AppxPackage

Method 3 : Edit the registry key

change both (Default) and LocalServer32 values in each of the following keys to the appropriate path for your installation of Outlook.
