We use Outlook at work which works fine for us. But, I tried to help my boss set up a second account that is gmail-based and it was a nightmare. We did all the things it said to do (flagged it to turn on imap, specified the proper smtp and imap servers, etc.) and it would not work. It kept warning us that we were trying to access his account and we'd tick that it was him and not to worry but it would not work. Weird thing is it wouldn't let us use the built-in Windows 10 email client either. I finally just slapped a gmail web link onto his task bar and told him he was stuck with that. Ugh.
