Office365 Problem

Hi. I can’t get my office365 account to work. I’ve tried signing in by adding account and choosing Office365 and I get this error.

Authentication Error - Check your username and password. (SMTP)

When I try signing in using IMAP I get this error with View Log

Authentication Error - Check your username and password. (SMTP)View Log

I have set it up using the settings you provide on your website. Below is the output from the log. For your info, I’ve set my account up on Samsung Email and after Mailspring failed I downloaded BlueMail for linux and had no problems at all with it. I’d much rather not have to have two email programs and I’d rather use Mailspring since I’m paying for it, so any help you can give me to get it up and running would be much appreciated. Thanks.

The IMAP settings show successful
