Current-era Microsoft continuing to push the boundaries of consent.
Microsoft Edge is a good browser but for some reason Microsoft keeps trying to shove it down everyone’s throat and make it more difficult to use rivals like Chrome or Firefox. Microsoft has now started notifying IT admins that it will force Outlook and Teams to ignore the default web browser on Windows and open links in Microsoft Edge instead.
Thunderbird is a pretty decent client, and OSS to boot!
I still use Thunderbird for my personal email because honestly it’s the best email client I’ve used, and I tried all the popular ones (including Outlook, eM Client, Mailbird, Postbox, Windows 10 Mail, and others). In particular, I have filter rules (Sieve) that filter emails into folders, and many of the clients don’t handle folders well.
On Android, I haven’t found any email clients anywhere near as good as FairEmail. It’s free and open-source, and has every feature you’d need. It directly connects to your provider’s IMAP server so messages don’t have to be relayed via a third-party or Google’s servers.
