Microsoft Outlook

It's fine to use in the browser, but they do not play well with IMAP, such as Thunderbird. I think this is intentional to try to move more people to using the Outlook Client, since many people have to use Outlook for work.

It is the only email that I ever have problems with connecting to Thunderbird, and it's a common problem based on Thunderbird's Github issues. The alternative is incompetent programmers.

This is the worst email client there is, and it is not close. Look up the microsoft store page for this, it's so bad that microsoft is actually lying about the average rating lmao they claim it's 4.7 stars when it's not even 3.

I would actually use Outlook for Mac, because I'm used to Outlook for windows through my work, even if the Mac version lacks some of the functionality (stupid example of Windows trying to force you into buying a Windows pc, Mac does this all the time).

BUT in the Mac version, you cannot send images in a mail as attachments!!! They always come up inline. And there is No. Way. To. Change. This. It drives me crazy? Why would you make such a stupid decision?

Still can't sync with Google Contacts even after years of broken promises. Sticking with Thunderbird as it's 99% of what I want.

Outlook is the best email, calendar, and contacts client I've come across. Unfortunately I'll be dropping it because it's now bundled with their version of AI to steal your email contents and contacts.

One of the best mail software that exist. A lot of functionalities that allows me to keep a good organization, and be focused on the subjects that matter the most.
