This took quite a while to debug, as Thunderbird has no built in options for connecting to Exchange servers, hence you have to set up IMAP and SMTP.īelow is my working configuration at the time of writing. For some reason, Office365 domains are not recognised by default by Thunderbird and such the automatic configuration doesn't work.

If this is the first email account setup on Thunderbird it will automatically open up a welcome window, where you will need to select Skip this and use my existing email. Recently I had to use an Office 365 mail account with Mozilla Thunderbird. Setting up an Exchange account in Thunderbird is slightly different to other email clients, as you have to setup the account manually.
