If the DLP agent software is unable to repair the outlook plugin " otlkplginst " you will need to reinstall or upgrade the DLP Endpoint agent.
Answer: Uninstall the DLP agent software and reinstall it Run the
AgentInstaller.msi manually to repair the agent installation should fix the issue, after which the Endpoint Block Policy should work successfully (i.e. the agent displays the pop-up block and blocks the confidential email.)
Uninstall the agent fully, create a new agent package, and deploy it manually to the system. This will reinstall the DLP agent along with the Outlook plugin.
If the MSI fails to reinstall successfully the agent and its components, including plug-ins, investigate the cause of the failure of the MSI installation package.
