I tried to get logging to work but even though I was logged into the Domain administrator acount it would not let me. I tracked down where the share was and added Domain Administrator with read access. This still yeilded a error message about permissions when i tried to enable logging and would not allow me to enable logging.
This morning im having a vendor do a defrag on the exchange store as i was advised this could be the issue but the exchange store he said was only 5GB.
The message box about granting read access isn’t a problem. You will get that warning message when you turn message tracking on, so it should be enabled. Have you tested searching for any emails sent out after getting the warning message?
