What is currently my best and most screen reader accessible option for working with Microsoft 365-hosted mail (Exchange Online) when running Linux? I’ve enabled IMAP and SMTP access in the Exchange Online configuration. It’s my Microsoft 365 subscription, which I recently upgraded to include e-mail, Microsoft Teams, etc., and intended for professional/career-related use. However, and for good reasons, Microsoft now requires the use of OAuth 2.0 authorization for both IMAP and SMTP connections. My options so far appear to be as follows. Mozilla Thunderbird, which I’m already using with my Linux-hosted IMAP account. Unfortunately, authentication in Microsoft 365 is currently an open bug which is being actively worked on by Mozilla, introduced in the most recent Thunderbird release. I expect this is my best option, and I can afford to wait a while for them to resolve the bug. Evolution: not very accessible with a screen reader, as I recall. DavMail: This is another possibility. It essentially accesses Microsoft servers and makes mail, contacts and calendar available locally via their respective protocols (IMAP, SMTP, CalDAV/CardDAV). I don’t know how reliably it works with Microsoft’s current authentication and authorization scheme, though. The outlook.office365.com http://outlook.office365.com/ Web interface: probably workable, but not ideal - I would prefer to have both of my mail accounts in the same client. Comments welcome.
