Mautic Version : 2.8  
  
In email setting we added an Office 365 account to send and retrieve emails.  
  
  
  
Test connection is ok.  
  
Send test email is sent correctly and I receive it in my inbox.  
  
  
  
When I try to send email through contact or campaign I get the following message :

Quote:

Failed to send to xxxxxxx : Failed to authenticate on SMTP server with username "xxxxxxx" using 0 possible authenticators

  
We were using Amazon SES before and everything was ok. When migrating to Office we had an issue.  
  
Any idea bout this issue ?
