From Windows Mail (Mail and Calendar) to Thunderbird

Microsoft has discontinued the Windows Mail and Calendar apps. They have not been supported since 31 December 2024. Windows suggests the new Outlook as a replacement, which sends your mail through the Microsoft cloud. Don't want that? Then Thunderbird is a good choice.

Your mail

The Mail app almost always used IMAP. This means your mail is stored on our server, so you don't need to import anything:

1. Install Thunderbird (see Installing Thunderbird on Windows, Mac and Linux).
2. Add your email address (see Adding your email address automatically). Your folders and mail appear automatically.
3. Is everything working? Then remove the account from the old app, or stop using the old app.

Can't remember the password for your email address because the old app saved it for you? Set a new password (see Changing the password of an email address) and enter it in Thunderbird and on your other devices.

Your calendar and contacts

The Calendar and People apps usually stored your appointments and contacts in your Microsoft account (Outlook.com) or in another online account. Export them from there and add them to your WebOké Nextcloud (see Moving your calendar and contacts from Google, iCloud or Outlook (ics and vCard)). Then connect them to Thunderbird (see Adding your Nextcloud calendars and task lists and Adding your Nextcloud contacts).

Tip: See Tour: mail, address book, calendar and tasks for how the Thunderbird screen is laid out. Many things look slightly different from the Mail app, but they work the same way.
