 Error after sending EHLO xxxxxx:4435 : 501
-the problem is not into your authentication because error is before that, at very begin of protocol. Try to go on Home - Setup - Other and add MAIL_SMTP_USE_FROM_FOR_HELO to value 1 so Dolibarr will use the domain in the from email as the HELO string. With 0, Dolibarr will use "smtp.office365.com" that may be refused.
+the problem is not into your authentication because error is before that, at very begin of protocol. Try to go on Home - Setup - Other and add MAIL_SMTP_USE_FROM_FOR_HELO to value 2 (default on recent versions) so Dolibarr will use the domain defined into conf $dolibarr_main_url_root of you conf.php file as the HELO string. Use 1 to use the domain in the FROM email. With 0 (old versions), Dolibarr will use "smtp.office365.com" that may be refused.
