The extension for Thunderbird doesn't work right. I have 6 exchange/office 365 email accounts for work. The extension can handle only 1 and if you add more than that it throws a tizzy. I had to contact the developer because I was having issues, they said they are working on a fix for adding more than 1 account..... There is no reason in 2021 now 2022 TB is not handing exchange account natively. This is not 15 years ago, MS gives the code out now to connect with exchange. TB still has not moved on handling signatures in email since they first began. TB seems to be stuck in 2010
Evolution is a mess.. it's outdated and the UI is horrid. It took evolution 2 days to sync all the emails from my accounts. It is even worse than TB IMO on all accounts. From my understanding only 1 person is left as the dev on Evolution and it shows.
I ended up just doing a Virtual Box with Windows 10, installed my Outlook and never looked back. Plus I use Adobe pro so I use that for my PDF's and I installed my Brother utilities center for my printer/scanner since sorry to say Linux still hasn't left 2002 for printers. Xsane looks and acts exactly like it did in 1999 when I first started in Linux.
Save yourself the grief, wasted time and energy just do a VB with Windows.


but since I use google calendar for meetings and a regular imap server for business to me Mailspring is almost perfect.
