I use different web interfaces to access Gmail, Hotmail, ProtonMail, Disroot, etc. However, I would like to use a single client to receive all my emails. Which desktop programs would you recommend for Linux, and which apps would you recommend for Android? I need them to support all of these email boxes. From what I’ve read around here, most people recommend Thunderbird for Linux, Mutt for power users, and K-9 Mail for Android. However, the first thing I noticed when opening K-9 Mail is that it doesn’t support Hotmail accounts.
Looking online Hotmail supports IMAP, pop and SMTP. So you should be able to set it up.

Looks like it just uses the outlook settings.
