You will probably find it hard, if not impossible, to add accounts from providers that require modern security or authentication standards. A W10/11 PC can be had for under US$200.

Thunderbird 52.9.1 and Firefox 52.9.0esr were the last to still support the then already EOL Windows XP and Vista.

Perhaps you could dual boot with a light Linux distro (avoid KDE and GNOME desktops) though there are not many 32-bit current Linux distros now. However if your CPU is 64-bit then you have many more options.
