On January 28, 2013, Apple released iOS 6.1 for selected models of the iPhone and iPad. Apple iOS 6.1 contains a bug that causes problems for users who connect to Microsoft Exchange email.
This bug can affect the performance of your entire email system. The bug causes the server to repeat a process that eventually uses all of the computing power of the server. Everyone will see a gradual slowing of the email system, and finally it would no longer be available.
This bug can also cause your iPhone or iPad to run hot and drain your device’s battery.
If you use an iPhone or iPad to connect to your email system, please read the following carefully:
· DO NOT upgrade your Apple iPhone or iPad to iOS 6.1 until Apple releases an update that fixes this bug. OCIO will let customers know when the bug fix version of the iOS is released. (Note: Apple released iOS 6.1.1 today, but it DOES NOT address this issue.)
· If you have already upgraded your Apple device to iOS 6.1, please disable synchronization of your calendar until Apple releases an update that fixes this bug. iOS users can do this by tapping Settings, selecting your email account, and setting the Calendars to OFF.
· If you do not turn off calendar synchronization, please do not use your Apple iOS 6.1 device to process or initiate any calendar entries until Apple releases an update that fixes this bug.
