This article covers a recent update from Microsoft for Outlook on Windows regarding the synchronizing of roaming email signatures. Read the full announcement regarding Outlook Roaming Signatures from Microsoft’s Support Website.
The new Outlook roaming email signature feature enables users with a Microsoft 365 or Outlook.com account to sync their Outlook signature across their different devices. For instance, when you create your own Outlook signature in your Office PC 1, then that signature will also be available in Outlook in your Office PC 2, if you have one.
The first release of this feature explicitly addresses Outlook on Windows PCs. This means that Outlook online, on mobile devices and on Mac computers will not be covered by this feature, initially.
In addition, this feature synchronizes the default signatures for new and reply messages for each user account. This may be an issue for those using shared accounts as they may have different users with different signatures.
The roaming signatures feature will be available to users on Microsoft 365 or Outlook.com so only users on Microsoft 365 will be affected. If clients host their own Exchange Server, the feature will not be applicable.
To disable the Outlook Roaming Email Signature synchronization feature manually, launch the Windows Registry Editor (RegEdit) and browse to the following location:
Right-click anywhere on the right panel, select New then select DWORD (32-bit) Value. Enter the DWORD name: DisableRoamingSignaturesTemporaryToggle
Double click the new entry to edit it and change the Value data to 1. Click OK to save, then close the RegEdit window and restart Outlook for the change to take effect.
Alternatively, you can download the registry editor script that inserts the needed registry value using the button below (at your own risk of course). Be sure to have a working backup, just in case.
System Administrators can choose to use the Outlook Roaming Email Signature synchronization corresponding Group Policy location to the same effect:
This value is temporary, and will be deprecated once an API is published allowing software vendors and administrators to set the value of signatures.
