Microsoft officially offers workarounds for iOS 6.1 Exchange errors including blocking & throttling iOS users

We reported on Friday that AOL had informed its corporate employees via email that it would be temporarily disabling the ability to manage meetings with Exchange on iOS devices running iOS 6.1. AOL confirmed that it was working with Microsoft and Apple to fix the “continuous loop” bug, and many had highlighted the problem on Microsoft’s forums. It doesn’t appear Apple addressed the issue with its recent release of iOS 6.1.1, and Microsoft has now published an official support document to detail workarounds for the bug.

When a user syncs a mailbox by using an iOS 6.1-based device, Microsoft Exchange Server 2010 Client Access server (CAS) and Mailbox (MBX) server resources are consumed, log growth becomes excessive, memory and CPU use may increase significantly, and server performance is affected. Additionally, Office 365 Exchange Online users receive an error message that resembles the following on an iOS 6.1-based device: Cannot Get Mail, The connection to the server failed.

Microsoft suggested a few workarounds for the issue while it waits for Apple to fix the bug. First, it informed customers to “not process Calendar items such as meeting requests on iOS 6.1 devices. Also, immediately restart the iOS 6.1 device.” If problems with Exchange continue, Microsoft recommended and provided instructions for removing and recreating the device partnership, creating a custom throttling policy for iOS 6.1 users, or blocking iOS 6.1 users entirely.

Microsoft said it is working with Apple to resolve the issue and recommended customers “open an Enterprise Support case with Apple”: Read more

iOS 6.1.1 build 10B145 being rushed to address 3G performance and enterprise concerns, some carrier testing completed

Vodafone-iOS-6.1-

Following reports about some carriers in Europe issuing warnings not to upgrade to iOS 6.1 due to issues with 3G performance, it seems a fix is already in the works. The issue was not just with 3G through carriers such as Vodafone and three in Austria, many users in Apple’s own forums complained of similar problems, degraded battery life, and more. Users have also had problems with Exchange support, causing AOL corporate to temporarily disable the ability to manage mobile meetings from iOS devices running iOS 6.1.

Today, a report from German language blog iFun claimed that carriers have already completed testing a 6.1.1 update to address the bugs and a 23MB update carrying build number 10B145 should be available over-the-air soon:

After ifun.de this information is already in version 6.1.1 of the night on Monday as “Testing Complete” and should be offered the iPhone community with little flow as a wireless update. Sources which are applicable in the past on the issue dates of iOS 6.0.2 and iOS 6.1 as well as the eradication of the “SMS spoofing problem” have informed, indicate the large 23MB update with UMTS-compatible.

Apple’s first beta release for 6.1.1 was released last week with build number 10B311.
