Mail Submit Permission error

[Tony Rogers]

When I am trying to set up a new email integration i am getting an error when trying to send alerts to Opsgenie. Im receiving the error:

Client does not have permission to submit to this server. The server response was: 4.7.1 <Integration address>: Relay access denied

Does anyone have any experience with this issue? Id be very grateful for some guidance! Many thanks!

Hello @Tony Rogers ,

This is Shashwat from Opsgenie support and here to help! :) 

This error looks like it's an issue on the Microsoft 365 side when sending an email to an external address.

Here's a document link I found that helped resolve this issue previously:

Could you please try the resolution steps to see if it fixes the issue on your end?

Best,
