Exchange 2010 and IOS 6.1 RRS feed

  • Question

  • I received an email from one of my colleagues warning not to upgrade to iOS 6.1.

    Working with Microsoft and Apple, they have identified an issue in IOS 6.1 that if a user updates, deletes, modifies, accepts any calendar entry from their i-device it causes problems with the Exchange server that impacts all or many other users with a multitude of different problems.  There is at this time no resolution from Apple/Microsoft.

    Was wondering if anyone else have this issue.

    Should i quaranteen Ios 6.1

    Thanks,

    If you want block iOS6.1, that is a decision your company will have to determine yourself. Note that there is no supported way to downgrade iOS 6.1 to a lower level, so if you block those devices, your users will have no way to get mobile mail unless they have not upgraded to 6.1 or use a different mobile vendor product.

  • Hi,
    Yes, I have seen it and below is an output taken from 1 day that clearly shows the problem.

    I used: A script to troubleshoot issues with Exchange ActiveSync
    ...to get that information.

    Workaround: To recreate the EAS Partnership on the devices.

    UPDATE: See: Apple iOS 6.1 upgrades result in excessive transaction log growth

  • Yes. Agree with Martina. Here is what seems to work. No guarantee it will work in all cases

    Use Exmon

    http://www.microsoft.com/en-us/download/details.aspx?id=11461

    to track down those iOS 6.1 users generating trans logs, then Remove-ActiveSyncDevice to remove the partnerships. The parnterships will be recreated automatically.

  • Thanks guys.

    We had a few issues before with iPADs and ios 5 i believe where users would accept and modify meetings from ios thus corrupting some of those meetings. running MFCMApi confirmed that some Flags were missing.

    We always guided users to not use ios/android build in utilities for meeting but instead to use OWA or outlook client.

    This looks like a diff. issue.

  • Yea, problems with Iphones and Calendaring seems to be a never ending story, but its clear to me that IOS 6.1 made the problem worse. Haven't seen it that much on Android devices.

    Isn't that something that Apple would know?

  • IOS 6.1.2 was released to hopefully address this issue.

  • after testing...IOS 6.1.2 does not fully address the issue.  The fix may come in IOS 6.1.3

  • We have also seen evidence that 6.1.2 doesn't resolve the issue as it has recurred in our testing and live environments. Our users are on 6.1.2 (10B146) was adjusting a single meeting of a recurring series with iPhone and the excessive logging condition came back. We identify users with Exchange User Monitor and disable their active sync to protect the server and then clear the log files with a backup.

    Is anyone else reporting or seeing that the problem is not fixed.

  • Per Tkoeppe and previous,

    We run Exchange 2007, and I can confirm that the iOS 6.1 calendar issue was impacting our organization. Our local MS TAM advised that the issue only impacts Exchange 2010, but I dispute this, as we've seen and taken action on iOS 6.1 devices causing the same problem.

    We so far have 1 case, where I investigated the same type problem (11.2 GB of TLOG in 1.5 hours), traced via 'ExMon', to a user that had both an iphone and ipad, and both had iOS version of 6.1.2 reporting, via :

    Get-ActiveSyncDeviceStatistics -Mailbox <id>

    If anyone else can verify this please jump in!
