Hello Everyone,
Yesterday I posted about Exchange 2010 not retaining delivery reports for very long. I did some more testing and some more research and discovered that we are only able to pull delivery reports from an hour to a couple hours earlier. Anything sooner will not generate. I have looked at the transaction logs and the logs still exist but will not have any information on who sent or received the message, just that the message has an EventID of SUBMIT. Again I ask for any advice any of you can give me on troubleshooting this further.
