Steps to Sync Thunderbird with MS Outlook 365

  • Log in to your Outlook 365 account using your credentials.
  • Go to “Settings” and click on; “View all Outlook settings.”
  • In the settings panel, navigate to “Mail” > “Sync email.”
  • Under the “POP and IMAP” section, enable the IMAP.
  • Save all the changes to exit the settings.

Step 2: Set Up Thunderbird: Once you have enabled IMAP access in Outlook 365, it’s time to configure Thunderbird to sync with your Outlook account:

  • Launch Thunderbird on your computer.
  • If you haven’t set up any email accounts in Thunderbird, you will be prompted to create a new account. If you already have existing accounts, go to “File” > “New” > “Existing Mail Account.”
  • Enter your name, Outlook 365 email address, and password.
  • Click on “Continue” and let Thunderbird automatically configure the settings.

Step 3: Manual Configuration (if automatic setup fails): If Thunderbird fails to configure your Outlook 365 account automatically, you can set it up manually:

  • During the account setup process, click on the “Manual config” button instead of “Continue.”
  • Select “IMAP” as the incoming server type.
  • Enter the following details:
  • Incoming Server:
  • Incoming Port: 993
  • Incoming SSL: SSL/TLS
  • Outgoing Server:
  • Outgoing Port: 587
  • Outgoing SSL: STARTTLS
  • Authentication: Autodetect
  • Click on “Re-test” to verify the settings.
  • If the test is successful, click on “Done” to finish the setup.

Step 4: Syncing Folders: By default, Thunderbird might not automatically sync all folders from your Outlook 365 account. To sync all folders and ensure proper functionality, follow these steps:

  • In Thunderbird, go to “View” > “Folders” > “All.”
  • Right-click on your Outlook 365 account in the Thunderbird sidebar and select “Subscribe.”
  • Check all the folders you want to sync with Thunderbird.
  • Click on “OK” to save the changes.
