I ditched them for OneDrive which comes with an Office365 subscription. OneDrive is buggy, has file naming issues (on MacOS at least), is a memory hog, and has a host of other issues. So I tried iCloud+ which comes with AppleOne subscription, and it lacks some of the sharing/directory collab features I wanted.

So yes, there are alternatives, many of which are free or included in other subscriptions, but they lack the focus of Dropbox, which Dropbox itself nearly lost when it tried to become something beyond file storage, versioning, and sharing.

How do you use Office365 specifically email?

I only use it for one of my lesser used domains and it is the worst email/app experience I have had in ages.

For some reason the outlook app went blank and had to resync. Missed a really important email. It gets like 100 MS update emails which have zero relevance to me and then it sends random emails I am not sure how to unsub from. It shows notifications for all those random emails and actual important ones get lost.

I got it for the 1TB storage space and teams(let me not even start on that). But now I am seriously considering moving that domain to gmail and zoom.

I use it on Mac with the built-in email client. On Linux, Evolution (via Evolution Data Server) supports Exchange too. I find their proprietary HTTP-based protocol much more reliable than IMAP and it's the only way to get push email on iOS using the stock client (it doesn't support IMAP IDLE and their proprietary equivalent is only open to GMail and Fastmail, no way to self-host and no other providers are supported).
