It's quite strange that one of my users sometimes (not all the time) got some (not all) of his emails several hours late, as compared to the very same emails got to other users in the list of "TO:" group. How could that happen? And why?
Could it be because his email box is too big (3 Gig) or what? Please help.
We are on Exchange 2010 and this user on Outlook 2007.
