I have had several iphones and always used them to access my hotmail.  I occasionally had problems with syncing which were easily fixed by resetting my account on my iphone. I currently have iphone 4s, which I had for a while.  It had no problem syncing to my hotmail account until yesterday.  I stopped receiving emails and when I looked at my inbox, it is only synced to July 2011.  I deleted account several times from my iphone and re-installed it with no effect.  It shows me all my folders and syncs some of them to within last few days, except for my inbox, which is stuck on July 2011.  Interestingly enough, I installed a different hotmail account and it synced with no problems. FYI in last few days I made no changes to my iphone or my hotmail account.

Any ideas??

Thanks,

Martin
