Yes, ArcGIS Enterprise Portal supports sending emails through Office 365. You will need to apply the settings below. When I have issues with O365, it's more often because STARTTLS is not selected as the encryption method. The attached image is a larger version of the one below.

Office 365 SMTP settings
  • Server name:
  • Port: 587.
  • Encryption method: STARTTLS.
  • SMTP authentication: ticked.
  • Authentication: your password

Hi, Are there any plans to support email integration with Office 365 through modern auth. Our administrators have disabled smtp basic authentication and will not turn it back on.
