Payal Arya
  • Updated

Description

You installed the Exclaimer Cloud Signature Update Agent to synchronize your client-side signatures with Outlook. However, you no longer want client-side signatures or you wish to upgrade to the Exclaimer Cloud Outlook Add-in. For this you need to uninstall Exclaimer Cloud Signature Update Agent. 

Uninstalling Exclaimer Cloud Signature Update Agent on a user's computer will:

  • Remove the program.

  • Stop deploying signatures from Exclaimer Cloud to Microsoft Outlook (instead, the user will have their signature applied by our server-side service, if applicable).

  • Remove any Exclaimer signatures from Microsoft Outlook.

  • Reinstate any original signatures that were archived for the user when the Agent was installed.

  • Reinstate signature options in Microsoft Outlook (local signature options are read-only when the agent is running)
