Email from Amazon SES to Company email hosted Office 365 - Not delivered

Hi,

   We are using Lambda function and SES to send email with Voice mail transcription and signed URL for Audio in email.

   It works fine with Gmail accounts. But it is not getting delivered to company email domain in Office 365.

  We verified those email accounts as SES.

 We tested in SES and it get delivered.

  I will appreciate your feedback on this.

Thanks, Selva

The below article provides common reasons why emails that you send from Amazon SES fail to be delivered. As a first step, I suggest to find out whether the issue is on the SES side or emails are being filtered at the receiving mail server side. To do this, you can follow the instructions under the section called There's an issue with the email recipient's server in the below article.

Thanks Nima for the feedback. We were able to figure out the root cause of the issue. But we need to find resolution from Office 365 side.

When SES use FROM (ex: sender@company1domain.com) and TO (ex: receiver@company1domain.com), office 365 doesn't accept the email and not delivering to receiver@companydomain.com mail box.

When SES use FROM (ex: sender@company2domain.com) and TO (ex: receiver@company1domain.com), office 365 accept the email and deliver it to receiver@company1domain.com mail box. We will work with MS Office 365 support team on this issue.
