Can't connect to Office 365 SMTP

Recently I've moved my FD support email address to Office 365. Now I'm unable to login to SMTP of that O365 account. I get this error: Error while authenticating the smtp server. Please verify server name, port and credentials

There are several similar topics here (all closed) and no visible solution:

I've enabled SMTP authentication for my email account in the O365 Admin section, but probably I'm missing something else... 

Can anyone please provide some assistance...

Thank you!
