  1. The console shows the admin address, for example https://192.168.1.57/. Accept the self-signed certificate warning for now.
  2. Sign in as admin / changeme. The wizard asks for a new password first.
  3. Work through network, ports, licence (or continue the trial), Microsoft 365 sign-in, and the sender mailbox.
  4. Add SharePoint routes, point your printers at the appliance's address on port 2525, and send a test scan.

The installation guide covers each step, including how to restrict sending to a single mailbox.
