Stopping Yammer raising an incident via email

Hi, @Jason Hier the only way I can think of that this would happen is if there's something set up on the Yammer side to send an email to your service desk's internal email address. You can check the email address for your Service Desk by clicking the Channels link in the sidebar:

This email address can be updated by the project admin or a Jira admin. You could in theory change the email address to see if that stops the Yammer tickets coming in, but it would also break the email channel for your legitimate customers. I'd suggest getting the email address, then contacting your Yammer admin to see if the email is included in a notification scheme or distribution group in Yammer.
