Duplicate Webhook Messages

Copper Contributor


Recently we have found that several of our third party tools that send messages to teams via Webhook are sending anywhere from 2 to 5 of the same message.

Being that the messages come from a  third party, we've asked them to look at it on their side, and can see the messages report a time out, so they get sent again, but the messages seem to be accepted even when the request is timing out.


I'm not sure where to start to troubleshoot on the teams side of things.  Any ideas?

I'm seeing the same, a webhook message sent via PowerShell script using the 

Register-ObjectEvent handler is sending duplicate messages, sometimes 2-4 of the same to Teams. 
We are using this code to post to Teams:
