How to connect to UWaterloo's new email system via any mail client

Step 1: Get Davmail.

  • I'm on Arch Linux, so I installed it from the AUR.

Step 2: Launch and configure Davmail.

  • Use O365Interactive for Protocol, and uncheck Local POP port, Caldav HTTP port, and Local LDAP port. Keep everything else as the default, and hit save.

Step 3: Setup your mail client.

  • I'm using Mailspring, which I believe is the best mail client I can get for free. [Not Sponsored]
  • Use manual config (IMAP/SMTP) to setup the account.
  • Use <your WatIAM username> as your username and your WatIAM password.
  • Use localhost as the server.
  • Use the ports set in Davmail (1143 for IMAP and 1025 for SMTP by default).
  • Set any authentication to None.
  • The first time you attempt to connect, you'll get a Davmail popup and the UWaterloo adfs page will open. Login with your credentials, and paste the link you reach at the end into the Davmail prompt.

Step 4: Run it as a headless service.

  • Success! Your mail should now work. Davmail basically acts as an interpreter between the O365/Exchange network and IMAP/SMTP. As such, it must be constantly running to receive/send mail. Go ahead and exit Davmail. Copy the properties from your home directory to /etc with:
sudo cp ~/ /etc/davmail/
  • Add a davmail user:
sudo useradd --system davmail
  • Finally, start and enable the service with:
sudo systemctl enable davmail@<your-linux-username> && sudo systemctl start davmail@<your-linux-username>

That's it! Note: Always test and verify via the webapp before relying on any setup!
