Apple today released iOS 6.1.2, the latest iteration of the mobile operating system for iPhones, iPads and iPod touch devices, following widespread reports of errors caused by calendars connected to Exchange servers.
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).
Both Apple and Microsoft began investigating reports that those running iOS 6.1 update caused overloading on corporate Exchange email servers. Some enterprises complained that their newly updated iPhone or iPad were “causing excessive logging” on the server. As soon as the iOS 6.1-powered device was switched off, the problem mysteriously went away. But the affects of the bug also caused the battery life on the iPhone or iPad to suffer significantly.
It’s a cinch to grab the update. From your iOS device, simply navigate to Settings > General > Software Update and tap on Install Now.
