(apologies in advance if this isn’t the right community for this question)
I’ve been flirting with Linux on and off for about 15 years and I think I’m ready to make the switch mostly full-time. I use a laptop for work and have a Microsoft 365 plan with email and such. I need to replace that with something Linux-friendly and would much prefer something that works with a desktop email client. Easy syncing of email, contacts and calendar to Android is a must.
Proton seems like it might be a good option but the privacy features aren’t a huge selling point for me so I’m open to other options!
Google Mail/Calender/Workspace or what it’s called. Works perfectly in a web browser and you can connect Thunderbird or Evolution. Most people who use Linux professionally are on Google. And most other people, too. Microsoft is a niche player unless you are locked in.
You can add self-hosted and open-source stuff anytime, but you’ll need good email and calender that plays nice with the outside world, so Google. Maybe something like mailbox.org. Maybe you ISP’s email + Thunderbird + nextcloud + K9 on Android will do, but you do not want to self-host or experiment with email if your business relies on it.
Nextcloud works fine for internal file exchange (but so does google drive), internal calendar, many apps on top of it. It even has a web-based mail client, but personally I would not use this is as my primary business email unless you are a hosting pro.
