Migrate to Fastmail from Outlook.com

The following information makes it easy to move your data from Outlook.com into Fastmail, once you have chosen a plan.


Set up your email address and/or domain

The first step is to simply sign up with the email address you want to use with Fastmail.

If you don't own your own domain, you'll need to select an email address using one of Fastmail's domains.

If you have your own domain, follow our domain and email migration guide to learn how to transfer your domain, mail accounts, and aliases to Fastmail.

Transfer your mail

You can import all your mail from Outlook.com onto Fastmail. This is a one-time task to transfer all your mail, and may take some time to complete.

  1. Open the Settings → Import & Setup screen.
  2. Click the Outlook.com / Office 365 icon.
  3. Enter your email address and password for your Outlook email account, then click the blue Login to Outlook button.
  4. On the next screen, choose the options that suit you. You can also set up fetching and sending from your other account on this screen so you can continue to receive new mail from your other account, and send from your other address.
  5. Click the Migrate button.

Please note that imports can take some time, especially for accounts with large amounts of mail. Do not start another migration from your account while the first one is still running, as it will result in two copies of every message in your account. You can continue to use your account as normal while the migration is running.

When your mail is done importing, you'll receive a message from us letting you know. We'll also email you if there were any issues importing your mail.
