A friend of mine has just bought O365 for Outlook, Word, etc but couldn't get their 'blah@yahoo.co.nz' email setup. It kept asking for the password so they called me !

I logged in via the web browser ok and saw an automated email to say a login attempt had been blocked due to the request coming from an app not meeting modern security standards.....Outlook for O365 ?

I tried the solution which was to 'Allow apps that use less secure sign-in' and now Outlook can set the account up.

It's using IMAP/SSL settings, so what's all that about ?

Is Outlook using SSL/IMAP settings not considered secure ?
