Fair enough. Unfortunately some bosses force staff to have Outlook and/or Teams on their personal phones as well. I hate it.

The bullshit of hiding access to previously available features (i.e. editing distribution lists in the client version), to force migration is just evil, IMO.

they're

They just had their first major overhaul in the last decade+ and are looking pretty shiny:

Personally I haven't had a chance to check it out because I just use my browser for personal email & my work mail is hosted through Microsoft so there's no pretending not using Outlook at work does anything for me.

That said, I am eagerly waiting for them to give the same treatment to the soon-to-be merged Thunderbird & K9 mail so I can use that for my personal mail on my phone

I've been using Thunderbird for a good decade or more, and honestly it's got the best email filtering rules builder of any email client I've used. The spam detection has only gotten better at detecting junk spoofed emails over time, it also always displays the email address as well as the name so it's easy to spot when something funky might be happening and the recent UI tweaks they've been making are very well thought out. Oh and they added an option to export/backup your profile to a compressed archive so I no longer have to copy the same .thunderbird folder from computer to computer and every time I install a new Linux distro

Good as always for me. The only issue is syncing contacts and calenders with MS-Exchange Servers, for that you need plugins and I haven't really found a good combination, but I don't know if my workplace is at fault too.

The newest release is visually awful. It drove me crazy and I had to downgrade back to the last stable (102). The content density was wildly inconsistent and text would be squished in one area and really spaced out in another. The toolbar moved so action buttons were in the title bar area, away from where your mouse would be (compared to before) if you're interacting with your inbox.

Other than that, the old version works just fine. Multiple email accounts, calendar and contacts. It does the job. Minor nitpicks, like dark mode doesn't dark evwrything, you still have to manually change your reading window colours. But at least it's once and done.

I switched from outlook when MS announced the new plan for outlook and honestly it's been great.

Fantastic! I just wish they would get the Android version released sooner. Although FairEmail is awesome too!
