Deploy the signature update agent to users' computers

To synchronize signatures to Microsoft Outlook, Exclaimer's Signature Update Agent must be deployed to each user's computer. The agent runs in the background and synchronizes signatures at regular intervals.

There are two ways that you can deploy the Signature Update Agent to client computers: 

Unless you have a specific need to deploy via GPO, we recommend that URL deployment is used - this is the simplest method, and ensures that the agent is always up to date.

Note: To learn more about the Signature Update Agent, please see our Signature Update Agent article.
