Can some of you share experiences you've had using thunderbird with office 365? I may migrate a small business' email to office 365. I know 365 + thunderbird is possible as long as imap is enabled and that wouldn't be an issue. Mainly I would like to know how smooth it has gone for those that have tried it. I don't think the people at this org use the calendar feature of thunderbird. They would need email and contacts. I've used thunderbird + gmail many times and that combination works well.

Actually IMAP is not required, as long an EWS is enabled on the exchange server (most of them)

The OWL add-on and the Davmail utility. Both make accessing exchange (O365) possible without IMAP or SMTP. Mostly the newest issue is Microsoft removing access to SMTP to send mail. I understand admins can still re-enable it, but have no direct experience. Just reports from university students on how they can't send mail.

Calendar is also supported. OWL is proprietary and has an annual cost and excellent support. I can't say the same about Davmail, but it was incredibly stable once I got it up and running. The learning curve was fairly steep but my experience there is also probably almost 10 years old.

Thanks for the reply Matt. You mean enable EWS on office 365, correct? Or does msft refer to the email server used by office 365 as exchange? Is the takeaway that as long as one has admin level access, it's a smooth user experience with office 365 + thunderbird? I'd like to avoid a disjointed experience that one has using gmail with outlook, where google provides a sort of go between software to make it work well.
