Install the Exchange on-premises agent

Host requirements

1. 1A domain-joined Windows Server 2016 or later with .NET 4.8.
2. 2Read access to Active Directory over LDAP.
3. 3Outbound HTTPS on port 443 to our API — no inbound ports required.
4. 4Exchange Management Shell installed on the host.

Install

1. 1Download the agent installer from Setup and run it as an administrator.
2. 2Paste the workspace pairing token shown in the console.
3. 3Choose the transport servers the agent should register with.
4. 4Restart the Microsoft Exchange Transport service on those servers.

Hybrid

Run the agent alongside the Microsoft 365 connector. Mailboxes are matched by primary SMTP address, so a person keeps the same template through a migration.
