Apple iOS 6.1 issues with Exchange Server

Microsoft released a kb detailing issues with Apple iOS 6.1 and Exchange server high transaction log growth.

Rapid growth in transaction logs, CPU use, and memory consumption in Exchange Server 2010 when a user syncs a mailbox by using an iOS 6.1-based device: http://support.microsoft.com/kb/2814847

This has been an issue since last week and the only solution that worked for me was to remove the device partnership for the user.

To know details on which OS the user is running, run the cmdlet:

 

Get-ActiveSyncDeviceStatistics -Mailbox username |fl

FirstSyncTime         : 12/2/2012 10:48:04 PM

LastPolicyUpdateTime  : 2/12/2013 12:23:29 PM

LastSyncAttemptTime   : 2/12/2013 1:37:16 PM

LastSuccessSync       : 2/12/2013 1:37:17 PM

DeviceType            : iPhone

DeviceID              : ApplDNTJxxxFGSED

DeviceUserAgent       : Apple-iPhone5C1/1002.143

DeviceWipeSentTime    :

DeviceWipeRequestTime :

DeviceWipeAckTime     :

LastPingHeartbeat     : 1009

RecoveryPassword      : ********

DeviceModel           : iPhone5C1

DeviceIMEI            :

DeviceFriendlyName    : White iPhone 5

DeviceOS              : iOS 6.1 10B143

DeviceOSLanguage      : en

DevicePhoneNumber     :

Identity              : user@domain.com\AirSync-iPhone–ApplDNTJxxxFGSED

To get results for all users, let’s use the cmdlet and filter using excel:

Get-CASMailbox -ResultSize unlimited -filter {HasActivesyncDevicePartnership -eq $True} | % {Get-ActiveSyncDeviceStatistics -Mailbox $_.identity} | Select-Object Identity, DeviceOS, DeviceType, DeviceID, DeviceUserAgent, LastSuccessSync | Export-Csv “C:\All_Users_EAS_Feb_2013.csv”

If you need to find all users running iOS 6.1, use the cmdlet:

Get-CASMailbox -ResultSize unlimited -filter {HasActivesyncDevicePartnership -eq $True} | % {Get-ActiveSyncDeviceStatistics -Mailbox $_.identity |where {$_.DeviceOS -match “6.1”}} | Select-Object Identity, DeviceOS, DeviceType, DeviceID, DeviceUserAgent, LastSuccessSync | Export-Csv “C:\All_Users_EAS_Feb_2013.csv”

Once we have the output, we should send a notification to all iOS users instructing them not to update their mobile devices.

Now we either have an option to remove mobile device partnership for users or block all iOS 6.1 connections to Exchange using the Allow/Block/Quarantine list method detailed here:

########UPDATE##########

Apple has acknowledged the issue and released an update this morning;

iOS 6.1: Excess Exchange activity after accepting an exception to recurring calendar event: http://support.apple.com/kb/TS4532

The solution they are qouting is to remove and re-add calendar from the device but for me, I would remove the partnership from the server and resync as MS KB suggests.

Another update is that – the iOS 6.1.1 released WILL NOT resolve this issues and only meant for some cellular and 3G issues with Vodafone network !!!

    Hi,

    when I run your PS commands I get this error.
    “Pipeline not executed because a pipeline is already executing. Pipelines cannot be executed concurrently.”

    Any idea why?

    Your CMDlet for finding all iOS 6.1 users does not work.

    Well it works for me… whats the error you getting?
    You need to run it from Exchange management shell and if you have e2010 users and E2007 users, run it separately from respective servers

    “Pipeline not executed because a pipeline is already executing. Pipelines cannot be executed concurrently.”

    This is the error I´m getting.

    Oh I got it now…

    When you copy the cmdlet a “?” comes next to 6.1 – some issue with wordpress I guess:

    Get-CASMailbox -ResultSize unlimited -filter {HasActivesyncDevicePartnership -eq $True} | % {Get-ActiveSyncDeviceStatistics -Mailbox $_.identity |where {$_.DeviceOS -match “6.1″}} | Select-Object Identity, DeviceOS, DeviceType, DeviceID, DeviceUserAgent, LastSuccessSync | Export-Csv “C:\All_Users_EAS_Feb_2013.csv”

    Just make sure the string looks like this:
    where {$_.DeviceOS -match “6.1″}}

  7. Johan H Says:

    Great, now I saw the Error when I cut-and-pasted.

    Works fine now! Thanks you for a great PS-line!

    Great script thanks!

    I also receive the error when running the commands listed above:
    “Pipeline not executed because a pipeline is already executing. Pipelines cannot be executed concurrently.”

    I manually typed the above out too. Apparently the command is being processed too quickly before some results are returned, so it needs a sleep command in there. Any ideas where that would go?

    Results still get sent to CSV but not sure if it is missing any. Am running Exchange 2010 SP2 with RU2.
