Apple solves the mystery of debilitating chattiness between Exchange and iPhones

Company will roll out second fix to iOS 6.1 in the near future, but for now, a settings tweak will have to do

Apple has solved the mystery as to why some iPhones and iPads are becoming excessively chatty with Microsoft Exchange Server. More important, the company has devised a short-term solution, akin to "flip the switch off and on" as it works on a software update.

When a user responds to an exception to a recurring calendar event -- say, a recurring Tuesday meeting that's postponed to Wednesday one week -- said user may find his or her device will begin generating excessive communication with the Exchange Server. This can lead to increased network activity and reduced battery life. What's more, users may find themselves locked out of Exchange because all of those logged requests look suspicious.

According to Apple, the flaw occurs with Microsoft Exchange 2010 SP1 or later, or Microsoft Exchange Online (Office365).

Apple said that it has devised a fix for the problem and will roll it out with the next iOS 6.1 update. In the meantime, the company advises that users not respond to exceptions to recurring events. If it's too late and your phone is exhibiting the aforementioned behavior, here's what you do:

  1. Go to Settings --> Mail, Contacts, Calendars
  2. Select the Exchange account from your Accounts list
  3. Turn the switch for Calendars to Off
  4. Wait 10 seconds
  5. Turn the switch for Calendars back to On

This will mark the second remedial patch Apple will release since rolling out iOS 6.1 two weeks ago. Earlier this week, the company pushed out iOS 6.1.1, designed to fix issues impacting cellular performance and reliability on the iPhone 4S. A number of iPhone 4S users had reported battery drain and overheating issues, possibly related to the iOS 6.1 update.
