Prevent duplicate emails using Exchange Online Rules
Hey, First time poster but long time lurker in this forum. I am in the middle to set my small company Exchange mail flow. One challenge I can't find the solution is to prevent duplicate email...
To be honest, I have no idea how to implement your suggestions. For the record, I'm using Exchange Online from Office 365, and I'm usually tinkering on the mail flow > rules section.
Can you elaborate more information for me?
Hes referring to a setting avail in on-prem Exchange:
I dont think Michel was suggesting you make any changes, just pointing out the feature. If you are getting duplicate messages in ExO, then you have a bad process sending those messages or something is broke in ExO and you should open a ticket with 365.
