I'm being placed under quite a lot of pressure from senior management over a relatively trivial issue. Basically the vast majority of users are complaining that they receive not read notifications (NRNs) for old emails and meeting requests in large numbers multiple times a day. I know something strange is happening because some are delivered at silly times in the morning (i.e 3AM or 4AM).
The problem I have is that these some of these NRNs are from meeting requests and messages that are 120 days old, so some users have deleted the original message so I don’t actually know if the NRN is from an email or meeting request.
This is typical of what users receive as a NRN:

But we already installed 'Update Rollup 6 for Exchange Server 2010 Service Pack 1' back in December, so I am not sure what we can do to fix this?
BTW we are running Windows Small Business Server 2011
