    Thanks very much. Followed your instructions, works great. Makes Thunderbird usable without having to re-enter hundreds of addresses.

    I continued Marks great work and created TbSync, which includes calendar support and a simplified setup process. More information can be found here:


    Task support is coming next.

    It didn’t work for me (Thunderbird 45.6.0). Everything looks fine, the addon synchronizes (status bar notification) but the Address Book is empty.

      I had a similar problem but after making sure that I had the details above correct and then closing and reopening thunderbirds I saw in the bottom right corner that it was syncing. Oh, and check your password is still represented by a number of dot ….. If not re-enter it.

      Good luck

    I was finally able to sync my outlook address to Thunderbird using this add-on. I have set Thunderbird on two systems. Thank you… Is there a setting to also download/sync the address book folders in the original outlook address book? Where is the setting to setup the schedule for syncing of the address book? Thanks for the help!

    The procedure is neat but it does not work as far as synchronizing the Outlook contact list and the Thunderbird list. I have worked with a friend and neither of us were successful.

      Did you check that your password still exists as it has a habit of disappearing. You may need to restart the program a few times too.

      Good luck.

    works like a charm!
    thanx. I needed a good email, contact and calendar prog for Win 10 (default MS mail prog in win 10 sucks bigtime!) and Thunderbird can deliver what I need.
    Though configuring synching with Exchange was not clear.
    Your instructions are and the contacts are now synched 🙂
    Now I need same for calendar …..

    I have tried these options, and also using dub-s@hotmail.com as suggested by an other contributor.
    Neither of these worked. Originally it imported gibberish addresses, which I deleted, and now it refuses to import anything despite telling me there are 152 contacts – which I cannot access.
    In the mail options there is no outlook folder, but does have an ancient Outlook Express one containing about 10 people from the past.
    Any help or suggestions would be much appreciated before I consider formatting with a large hammer?

    Looks like this is a winner!! I am migrating away from Outlook 2013 because of its instability with IMAP. I keep my contacts on Outlook.com so I have it on my Windows phone too. This now sychs that with Thunderbird. Thanks so much for making this work.

    Is there a way to sync the Outlook.com Calendar and maybe the Tasks also?

    Thanks for that.
    The s.outlook.com is a new one to me. And it works. Much better than the xxx-m.hotmail.com method.

      Thanks a lot for the comment Mark. And thumbs up for your wonderful add-on. It has saved my life and will definitely save many others from frustration.

    Definitely worth a try. Thunderbird isn’t a good email client if it doesn’t sync contacts by default. I think Contacts are an integral part of email which should be synchronized directly through IMAP or POP.
