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 additional addresses 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.
- Open the Settings → Migration → Import screen.
- Go to the Import mail, calendars, and contacts section and select Outlook.com / Office 365.
- Click the Sign in with Outlook button.
- A pop up window will appear prompting you to enter in your Outlook credentials, and then asking you if you would allow certain permissions for Fastmail. Click Allow to proceed.
- You'll then be asked what you want to import, and if you'd like mail to continually be fetched from your Outlook account. Please select the options you'd like.
- Click Do it.
Note: When importing messages from Microsoft 365 or Outlook.com, please ensure none of your folder names include a forward slash. Due to a limitation in Microsoft’s IMAP implementation, folders with a forward slash in their name cannot be accessed or imported. To ensure all your data is migrated successfully, rename any such folders before starting the import.
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.
