The ability to sync your signature settings between the Cloud (or OWA) and your Outlook Desktop client is now available in Microsoft 365. Previously signatures saved in the Outlook Web App and the Desktop client were independent and if you wanted them consistent a 3rd party application (such as Exclaimer) would be required.
With the new settings (currently in preview as of October 2022 and available to the insider update channel), you can now ensure your signature is consistent across your cloud apps and desktop apps.
Tracking the Signature Cloud Settings feature update

How the signature cloud sync feature works
With the latest build of Outlook, the design has changed so that is matches that of the Outlook Web App. The signature sync automatically happens both ways, so whether you update the signature in the cloud or in the desktop client, it will be the same.
You should know that if you change the signature in the cloud, you will have to restart the desktop client for it so take effect. (this would be a similar process if you was using a 3rd party signature product).
How to disable the Outlook roaming signature feature
Roaming signatures is not for every organisation, some organisations with large amounts of users may not necessarily want the additional administrative/training burden, especially if they are yet to set expectations for their users on the new feature. Also, if you are using a 3rd party product which is heavily used by staff, it may already be providing features which are not yet available in the new signature cloud sync feature.
To disable the feature, there is a registry key you must implement on the users workstation. This can be done through group policies, Intune, login scripts or another product of your choice.
2. Navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Setup
3. Create a new DWORD with the name DisableRoamingSignaturesTemporaryToggle
4. Set the Value to 1
