How to set up Outlook

The instructions and screenshots in this setup guide are for Outlook 2016. However, previous versions of Outlook are very similar, and you should be able to follow the same steps to set up.

Outlook needs its own app password to access your information. If you use your normal password or your Fastmail two step verification password on an external account, syncing to an external service won't work and you will see a password error.

Set up your email

  1. Open Outlook. If this is your first account, it will ask you to open a new account. Enter your Fastmail address, select Advanced options and select to Enter your details manually.

  1. Click on your Inbox folder.
  2. Click on the FOLDER tab in the main menu.
  3. Click on IMAP Folders. A new window will open.

  4. Uncheck the box for show only subscribed folders, which will mean all folders are shown:

Contacts and calendars not supported

Outlook 2016 does not support CalDAV or CardDAV. You will need to use a third party plugin.
