  5. Making the most of Fastmail

1. Set up your email address and/or domain

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

2. Transfer your existing mailbox contents

You can transfer your current mailbox into Fastmail using two methods: IMAP or POP.

Mail that is held on the server is accessed via IMAP and we recommend using this method. This allows you to make use of our backup services; and lets you access your mail from any of your devices or from any web browser.

Mail that has been downloaded to the desktop and lives within an application is accessed via POP. POP will only download mail from your Inbox; it won't download mail that is directed to other folders you have created.

Mail held on the server (IMAP)

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

  1. Open the Import & Setup screen.
  2. Click the "Import mail from another service" link.
  3. Enter the following settings:
    • IMAP server: imap-mail.outlook.com
    • Username: Your Outlook.com email address, including the domain
    • Password: Your Outlook.com password
    • Use SSL: Yes
    • Remote server prefix: (leave blank)
  4. The "Folders" settings lets you choose whether to:
    • Import the mail straight into your existing folders, or
    • Keep imported mail separately in a new set of folders (you can then manually move the messages into your existing folders later), or
    • Select particular folders to migrate (you choose which folders after you push the migrate button)
  5. Click the "Migrate" button.

Mail stored on the desktop (POP)

If your old mail isn't stored on an IMAP server because you have already downloaded it to your desktop using POP, you can leave it where it is, or you can transfer it to Fastmail's IMAP servers for access through the web client.

To transfer mail in your desktop client to Fastmail's servers, log onto Fastmail from your desktop client and drag the folders containing your existing mail into the Fastmail account's folders. Depending on how much mail you have, this can take some time before the mail completes uploading to our servers.

3. Transfer your contacts

  1. Export your contacts from Outlook.com into a csv file.
  2. Import your contacts into Fastmail

4. Transfer your calendars

You need to manually export your events from Outlook.com into an ics file, then import this file into Fastmail.

Follow these steps to export your calendar from Outlook.com:

  1. Sign in to your Outlook.com Calendar
  2. Click on Share located at the top part of your screen and select the calendar which you’d like to transfer.
  3. Choose the option which says "Send friends a view only link to your calendar" then click on ICS: import into another calendar application.
  4. A new dialog box will appear. Copy the link.
  5. Open a new browser. Paste the link that you previously copied then replace the word webcal at the beginning of the address with http and hit Enter.
  6. A new dialog box will appear. Please click on Save to download your calendar’s ICS as a .ics file.

Follow these steps to import your calendar information to Fastmail:

  1. Import your calendar using the Import & Setup menu to bring it into Fastmail. Select the file you downloaded earlier.

If you had your calendar synchronised with a mobile device, you'll want to switch it to talk to Fastmail instead of Outlook.com. Use our instructions for common clients to get set up, or use our own Fastmail apps.
