I have several users that are experiencing the same issue with their iPads and iPhones.  When an update comes from their exchange calendar, the update is not going to their devices.  When a meeting is cancelled it also isn't showing up on the devices as cancelled.  I have not been able to replicate the issue but I'm now up to at least 10 users complaining of the same issue.

 

Has anyone experienced this?  Do you have any ideas on how to correct this problem.  I do know that this problem was seen in version 6.0.1 and that the fix was to upgrade the iOS.

iOS 6.1.4

    This issue seems to come up pretty often.   I've found a lot of the time it can be related to the cache *.ost file being corrupted on the computer which is host of the users Outlook account.  I would turn caching off, delete the file, turn caching back on and let it be rebuilt.  The other thing I do( as long as OWA is correct) is turn off calendar delivery under account settings on the iOS device, reset the device with home and power button, then turn calendar sync back on.  Neither of these are cure-it-alls by any means.  I think the real issue is the EAS protocol. Maintaining consistent Mail delivery to multiple endpoints is an extremely complex problem.  Some  Ways to mitigate are to educate users on Calendaring best practices

    and have them be careful deleting or modifying  intermediate instances of recurring appointments. Also, have only 1 delegate.  

     

     

    There are a  number of lengthy threads here about this issue that cover it in far more detail than I have shared here.  I'm not convinced there is truly a "fix" for this out there.  There is a lot of info on this issue and discussion in some older threads.
