Hi Xavier,
I can't directly answer your question but I had spent quite a bit of
time trying to make a Ruby script work with Office 365 SMTP.
This is the script that worked for us - maybe, something here will help?
smtp_host = 'smtp.office365.com'
smtp_port = 587
smtp_user = '[email protected]'
smtp_pwd = 'whatever-your-password-is'
smtp = Net::SMTP.new(smtp_host, smtp_port)
smtp.enable_starttls_auto
smtp.start("yourdomain.com", smtp_user, smtp_pwd, :login)
smtp.send_message(msg, smtp_user, to_mail)
smtp.finish
For reference, the start method uses this structure:
> start(helo_domain, account, password, authtype)
It was important for us to:
> make sure the smtp host was smtp.office365.com = yours seems OK
> port was 587 = yours seems OK
> STARTTLS was AUTO = yours seems OK
> make sure that the smtp.start used "yourdomain.com" = not sure if
you're doing this
> authentication was LOGIN = yours seems OK
Hope this helps.
Best Regards,
Mohit.

Hello
Recently a client has migrated all email accounts to send mail using
office365 server.
Now my programs can't send email using that server. Always get
"Error=535 5.7.3 Authentication unsuccessful"
I tried many options but always get error 553.

I configured Outlook and Thunderbird with supplied parameters with no
problem.
On that programs can set secure mode to TLS or SSL, but only works TLS.
I don't find how to configure ICS to work with TLS.
I would agree any help about it.
Thanks in advance
Xavi
