A number of articles/videos are reporting that Windows share is reducing. Windows 11 with its: push to cloud storage, AI, privacy issues, need to be actively online and linked to MS account etc. People switching to Android and phones is another.

I've been a TB user for at least 15 years (currently on v10). With 12 email accounts it's an indispensable tool for managing my affairs. I particularly like the Alt+F2 for accessing all my email accounts in seconds.

There is a trend to webmail but using webmail it would take me 30 mins as my email provider web interface does not prompt password manager to enter the passwords and webapps are slow and rely too much on mice. TB has been very reliable (OK 1 feature I avoid as it looses my emails!).
I'm on Win 10 ESU so my thoughts are turning to moving to Linux and options:.

1. Wine: I did try TB under Wine many years ago and it seemed to work. There are now a number of Wine GUI front ends (e.g. Bottles, Phoenicis, Q4Wine)
   
   
2. Virtual Machine: I run a 16bit app in Virtual Box but only open a few times a week. Not tried TB and unsure if I / my computer could live with VB being open 10 hours a day (I usually have too many apps & windows open and need less!)
   
   
3. Other Windows under Linux options: A search indicates: Winboat (new),  CrossOver, WinApps (with RDP).
   
   
4. Other email client s/w: Search gives:  Thunderbird, Evolution, Mailspring, KMail, SeaMonkey, Geary, Blue Mail, Claws, Mutt, NeoMutt, Betterbird, Trojitá.
   Key features for me are: able to import messages from TB, multiple POP accounts in one interface, can handle 10,000s emails, filters, flagging/tagging.
   

TB users considering moving off Windows, what have you tried and found best?
