(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!
I've been on Linux desktop (Mint) for over a decade now. My company uses O365 for email, as did the organization before them.
I use Thunderbird with several add-ons: Mailbox Alert, Owl for Exchange (paid), Provider for Exchange ActiveSync, and TbSync. I honestly couldn't tell you which one or ones I find most useful - it's been so long since I've installed them, I don't remember which addon provides which functionality. My most recent install was Owl, for calendaring and because things got a wee bit fucky with O365 servers for a week or two last year. I have Thunderbird set to collect addresses when I reply to users. You can have it query AD for contacts, I think, but it tends to be a wee bit slow.
On my Android phone, I use the default Google Calendar app, and the Gmail app to query O365.
