Apple working on fix for iOS 6.1 bug that's choking Exchange servers

By , Network World |  Software, Apple, iOS 6.1

The Exchange glitch was not a fluke. Based on similar posts, and direct contacts with other IT managers, Tony Redmond, who writes the Windows IT Pro blog, "Tony Redmond's Exchange Unwashed," wrote a week later about instances of "excessive transaction log generation after iOS 6.1 devices are introduced into Exchange 2010 or Exchange 2007 environments. I assume the same is true for Exchange 2013 as the underlying cause is likely to be in Apple's mail app code that calls ActiveSync to synchronize with a user's Exchange mailbox, with some indications being that the problem is once again associated with calendar events."

The Microsoft support posting for Exchange confirms that this problem can and has developed, and that Microsoft and Apple are partnering to sort it out. But IT managers at a half-dozen companies and universities say that, while they're tracking these reports, for the most part these problems have not affected their users or networks.

The only one of this group to notice possible Exchange issues is Boston Scientific Corp., a leading medical device manufacturer based in Boston. It has more than 5,300 corporate iPads and 1,000 personally owned iPads, with some percentage in the process of upgrading to iOS 6.1. "There's been no rash of problems but the Exchange group has issued an advisory around iOS 6.1," says Rich Adduci, the company's CIO. "I don't think we've seen a ton of issues here, but definitely have had some reports, pretty inconsistent, and almost all tied to accepting or declining Outlook meetings using an iOS device," he says.

Others seem to have sidestepped this problem at least by not having large numbers of 6.1 devices or by using email and calendaring alternatives to Exchange.

"We only have one iOS user on 6.1 who is using Active Sync and they have not reported any issues nor are we seeing any on our server," says Nelson Saenz, vice president of IT for Active Interest Media, in El Segundo, Calif. They have just over 120 iPhones and about 30 iPads. "We are standardized on Good Technology for [managing] all our other mobile devices and have not seen any of the unusual activity that is being reported."
