Anyone having this problem aswell? Things been working fine, untill yesterday Evolution gave me this message for both my microsoft accounts:
Failed to authenticate: Failed to obtain an access token for “xxx@outlook.com”: Bad Request’
First I tried to solve this by removing the stored passwords in seahorse and re-authenticate, which gave a bad request. Then I removed both accounts completely (in settings); adding them again doesn't do a thing. I approve it in the browser, and then nothing.
I haven't made any chances to Zorin in the time between it working and not working.
Taggin in here as having issues logging in ZorinOS 18.1 ande m365 anything. Its clearly a micros*** design issue because em Client running in winboat auth'd perfectly. (Same pc).
Perhaps it is a good time to ditch Outlook if only used for personal use. Proton Mail has stated a few months back that Outlook is selling data to 3rd Parties when products are mentioned in the email message.
