hello guys,
After Google made updates to the security measures related to app access, I was unable to resolve the issue as no message could be sent from Odoo, and where I also set up Office365 as an outgoing mail server and it gives "Connection Test Succeeded! Everything seems properly set up!", and when I try to send a message (Unknown error: Mail Delivery Failed Mail delivery failed via SMTP server 'None'. SMTPDataError: 554 5.2.252 SendAsDenied)
Please advice
