Troubleshooting iPhone Issues with Calendars? It’s Might Be Your iOS

Last week we started a new mini-series on troubleshooting Exchange ActiveSync (EAS) clients, so it’s somewhat timely that one of the issues plaguing many Exchange admins who support iPhone and iPad users have been resolved. If you read our post last week on Troubleshooting Third Party ActiveSync Clients then you are already aware of the great page Microsoft maintains on known issues with other vendors’ clients. Just in case you missed that, it’s Microsoft KnowledgeBase article 2563324 and that’s a page I recommend you keep a close eye on, since it is updated frequently when new issues are discovered with EAS clients.

The issue we’re talking about is tracked on that page as Issue 1.2-An attendee becomes the meeting organizer. Essentially, if an iOS user (iPhone, iPad, or iPod Touch) changes the reminder for an occurrence of a recurring meeting. This impacts user whose device is running iOS 6 and Microsoft’s KB 2768774 offers less than realistic suggestions for many of us, including blocking iOS6 devices from connecting, recommending to our users not to modify items in their calendar, or not to update to iOS 6 (too late!) yet. Fortunately, there’s a fix.

This issues is a bug in iOS, not in Exchange. Apple recently released iOS 6.0.1 which contains a number of improvements, security updates, and yes, a fix for this issue. Here’s a list from Apple’s page at on the improvements and bug fixes in 6.0.1.

  • Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air
  • Fixes a bug where horizontal lines may be displayed across the keyboard
  • Fixes an issue that could cause camera flash to not go off
  • Improves reliability of iPhone 5 and iPod touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks
  • Resolves an issue that prevents iPhone from using the cellular network in some instances
  • Consolidated the Use Cellular Data switch for iTunes Match
  • Fixes a Passcode Lock bug which sometimes allowed access to Passbook pass details from lock screen
  • Fixes a bug affecting Exchange meetings

iOS 6.0.1 also addresses some security issues, discussed on this Apple web page Four CVEs are fixed.

  • CVE-2012-3748 Visiting a malicious website may cause the browser to crash or arbitrary code execution
  • CVE-2012-3749 Malicious apps may be able to determine addresses in the kernel
  • CVE-2012-3750 User with physical access may be able to bypass screen lock to access Passbook passes
  • CVE-2012-5112 Visiting a malicious website may cause the browser to crash or arbitrary code execution

iOS 6.0.1 is available for download through iTunes or wireless for users who have enabled that, and can be installed on any of the following devices.

  • iPhone 4S
  • iPhone 4
  • iPhone 3GS
  • iPad (3rd generation)
  • iPad 2
  • iPod touch (4th generation)

Users with older hardware like first generation iPads may be out of luck at this time. Considering my first gen iPad only hits its second birthday this upcoming Christmas, that is really quite disappointing. I won’t be asking Santa for an iPad Mini this year. I have my eyes on a Surface. What about you? Anything new on your must-have wish-list? Leave a comment and let me know. Your Secret Santa might be reading this too.
