Unable to create connector for Office365 Exchange

Question

My website server is blocked 587 port so I need to use the relay to send emails. I am planning to use a Windows Server IIS to make this, and I need to create a connector. When I created the connector, I got an error: "Error executing request. For this service offering, you can't create or update inbound connectors in your organization '79f86758-6cc1-4e5f-a76f-6ca0c2f44ef7'."

Hello, @子悦,

Welcome to the Microsoft Q&A platform!

Based on your description, I understand that you receive an error when trying to create an inbound connector in your organization.

Inbound connectors from on-premises organizations aren't designed to relay bulk email to the internet, this activity is considered a misuse of the feature. For more information , please refer to Inbound connectors from on-premises organizations FAQ" | Microsoft Learn.

Therefore, if you want to create In-bound connector in your tenant, you may need to contact our dedicated back-end technical team with your business justification. Our technical engineers then approve the legitimate usage and enable the connector for your tenant. To do this, you may need to create a support ticket in your tenant Microsoft 365 admin center, you can refer to Get support - Microsoft 365 admin | Microsoft Learn.
