  IERI (Yesterday) I informed you about the launch of a support page on the Microsoft website, on that page the American company offers users methods by which they can solve the system problem microsoft Exchange from iOS 6.1. Those from Microsoft stated that Apple is working with them to discover and solve bugs, and today the company from Cupertino to publisht a supporting document that acknowledges the existence of the problem. Apple also offers a possible solution for the problem, but claims that the iOS will be updated to solve it, but no one knows when it will be available.

When you respond to an exception to a recurring calendar event with a Microsoft Exchange account on a device running iOS 6.1, the device may begin to generate excessive communication with Microsoft Exchange Server. You may notice increased network activity or reduced battery life on the iOS device. This extra network activity will be shown in the logs on Exchange Server and it may lead to the server blocking the iOS device. This can occur with iOS 6.1 and Microsoft Exchange 2010 SP1 or later, or Microsoft Exchange Online (Office365).

* An exception is a change to a single instance of a repeating calendar event.

Apple has identified a fix and will make it available in an upcoming software update. In the meantime, you can avoid this bug by not responding to an exception to a recurring event on your iOS device.
