I was one of the people having problems over the last week and I am still having some problems.  I can get my current mail if I set my phone to sync up to one month however when I try to sync all my mail with no limit, my current email disappears and Outlook will load only the emailsl going  back to May, 2011 and earlier. I have deleted the account and installed it new several times with no change in the behavior. I can see all of the mail on my computer with no problem.  At one point I thought it was working okay because I had my current emails and older emails but soon realized that it was missing all of the emails between 7/13 and 5/11.  Everything was working perfectly before this past week!
