Give up on outlook already. Get a free gmail or hotmail account like everyone else is doing these days. You’ll get used to it in no time and you won’t miss outlook one bit.
Thunderbird works well and it’s free
You can try Thunderbird. I think it is still free. If you won’t by Outlook (office 365 is 100 bucks a year). Some companies also have an employee purchase program for $10 bucks or so for all the office products.
I have been using the same hotmail account for about 15 years and it is so nice NOT to have my overcrowded mailbox residing on my pc. So easy to read it online - and you can make subfolders, etc. just like the old outlook.
