My Exchange mailbox has suddenly and inexplicably stopped syncing new emails on my iPhone 5 and my iPad mini with Retina since last Tuesday.
I am not getting any visible errors on my iOS devices that would indicate that sync is failing or an error has occurred. Its seems like only the Inbox (sub-folders are unaffected) is not showing me emails newer than approx 2pm last Tuesday. I can view all the emails in other folders in this mailbox, including items newer than Tuesday and I can still send emails from this mailbox.
Both devices are on iOS 8 .1.1.
Outlook 2013 on my Windows 8.1 desktop is still functioning perfectly, as is Apple Mail on my Yosemite 10.10.1 Macbook Pro. I have also test the same mailbox on a Samsung Galaxy S4 running 4.4.2 which is NOT exhibiting the same behaviour, it too works fine. =(
We are running Exchange 2010 SP3 update roll-up 7 on Windows 2008 R2 x64 Std edition.
I have checked the logs for anything obvious and haven't found anything.
I have tried deleting the mobile devices associated with my mailbox in EMC and resetting up my account on my iOS devices one at a time but it has not made any difference. I still can only sync my inbox up to about 2pm last Tuesday.
I have tried deleting emails with large attachments too but that also has not helped.
I am running out of ideas and cant find any errors in the event log that are helpful. That's not to say there are none. Just that I can't find them. ;)
I would really appreciate any advice anyone has on this. If I have left out any detail please ask and I will answer them ASAP.
Thanks in advance,
