You are using Exclaimer Cloud client-side to create signatures visible to Microsoft Outlook users and want to disable the Outlook roaming signatures feature.
Exclaimer has released an update to the Exclaimer Cloud Signature Update Agent that will automatically set the registry key to prevent Microsoft from updating the mailbox, but you can also manually disable this feature or disable it via Group Policy.
