Hi, If a message is going to another user which was a delegate/any outlook rule. This user no more exists, and only NDR is going back to the sender. Because this is distribution group, i need to find the user who has any rule/delegate, i have checked from AD nothing helped. Can we find the user in the group who is forwording message to another user by delegate/outlook rule? Thanks SMF

Hi Syed, You can open the received email message properties from your Outlook, and also it's Delivery Report - to view all SMTP headers and all the sender information, groups expanded, receivers, etc. This should help on finding such tails. Vote if Helpful / Mark if Answer
