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:

I have done a search and found the following:

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

Did you see this note: Note The NRNs are not completely flushed until 120 days have passed after the hotfix is installed. Has it been 120 days since the update rollup was applied? –  Coding Gorilla Mar 23 '12 at 19:40
    
I did but I was hoping I would not have to wait 120 days! I have just checked when the update was installed (which was 103 days ago). Can anyone confirm that this will fix the problem once the NRN queue has been fulshed? and that there is no way of speeding this process up? –  Exile Mar 26 '12 at 10:02
    
It seems that your problem is exactly matching the one fixed by this update, so it seems reasonable that after 120 days your problem will go away. But I can't confirm for sure that it will. –  Coding Gorilla Mar 26 '12 at 17:10
    
@Exile Did it go away after 120 days? –  Mathias R. Jessen Apr 13 '12 at 19:15
    
As far as I can tell, Yes it has now 121+ days has elapsed! If I have anymore problematic NRNs from 120 days ago I will post here to let you guys know. I also made a post on technet about this which you can read here: social.technet.microsoft.com/Forums/en-US/exchangesvrclients/… –  Exile Apr 16 '12 at 11:20
