Find out when an email in Outlook Deleted Items was deleted

Thanks but that doesn't seem to do it - I added the 'modified' field to deleted items  as suggested but that just tells me it was last modified on Saturday 16th and I know for certain it wasn't deleted then.  
I had hoped the exchange tracking tool might do it but obviously that's not interested in the email after it's delivered to the mailbox..

I did some more searching and so far it sounds like that's the closest option, though as you found it's not always accurate.  Some people insist it works, and others will show proof it doesn't, so I suspect it may vary depending on what else is happening with your environment.  (smartphone synchronizing, virus scans, etc... anything else that may update the email and the timestamp along with it.)  Some of the discussions I've found out there actually come out and say "can't be done".  If you have enough access to server logs and traffic (maybe firewall logs?) there must be some way of tracking it though.  

If this is important to find, maybe it would help to use the Request Attention link below your original question and have the question added to other topics such as Digital Forensics to see if they have any more input?

Result is not a reflection on the answer given as it appears to be the best option available but it doesn't do what I need.  Thanks for your input though.
