How to install the Outlook (Classic) agent

The Signature 365 Agent for Outlook supports adding signatures to email so signatures appear directly below the email being composed, and for users to select an alternative signature if additional signatures have been assigned to them.

The Signature 365 Agent is available to use with Outlook 2016 / 2019 / 2021, and can be deployed using MSI or ClickOnce.

Important!

The Signature 365 Classic Agent is not compatible with "New" Outlook 365. The modern add-in is required for this version of Outlook.
