Dear Sir,

I have opened the question reagarding our exchange server 2003.  This problem is occurred after 8/18/2012 windows update in the Exchange Server,  I discover 4 updates on 8/18/2012,

Our server was working fine for all our mobile devices until those updates were installed, and then the problem is occurred, Mobile device is not able to receive emails from Mail server.  Please see those updates, one of updates, KB2705219, is updated about intelligent messaging filters for MS exchange 2003,  I don't know this will affect our mobile devices.

Please help us to resolve this issue, all mobile users are calling me for help "not receiving emails from exchange via Mobile active sync email account.

Here is opened question what I did on 8/25/2012,

Dear Sir,

Our coporate Exchange 2003 server was working very well for our staff's smart phones, iphone, and ipad.  Suddenly, Exchange server 2003 w/sp2 is not able to provide server active sync with our company smart phones using Active Sync exchange email to pull emails from exchange server into cell phone inbox at all. I check exchange server IIS Active Sync service is running.  If I configure a coporate email account with exchange active sync in a new smartphone or ipad, accounts are successfully created, but no email message, I can see smartphone or ipad active sync is turning and turning, but no message at all.  I don't know how to reslove this problem.  We have many department managers who are traveling and must need to know company emails in their cell phones and ipad.  Please help.

Thank you,

    Is only mobile phone affected or is it OWA and Outlook as well.

    Ideally you should remove the updates and restart the PC so you should first do that. Check the eventvwr for relevant errors if any.

    If they aren't getting emails, Exchange would generate events of Active-Sync, do you see any errors in application logs?

    Also, run Exchange best practice analyzer tool along with tests on

    Did you try uninstalling the KB from Add\remove programs ?
    Did you check the App or HTTP logs ?
    You can try to check active sync with the below URL

    We had the exact same issue and worked with Microsoft over the last couple days to identify an upgrade of Diskeeper as the culprit.  It just happened to be that the Microsoft patching reboot was the first reboot after the Diskeeper upgrade.  

    To identify the minifilter drivers being used:

    Filter Name                     Num Instances Frame
    ------------------------------  ------------- -----
    VirtFile                                0       1
    DfsDriver                                    <Legacy>
    DKTLFSMF                               15       0
    DKRtWrt                                15       0

    Open in new window

    And what volumes they are being used on:

    C:\>fltmc instances
    Filter                         Volume Name                    Altitude
    Instance Name
    -----------------------------  -----------------------------  ----------------
    DKTLFSMF                       C:                             366992
    Telemetry Instance

    Open in new window

    The DKTLFSMF on the C: volume was the minifilter driver identified as the possible culprit.

    We stopped the Diskeeper service and then ran this to detach it from the C: volume:

    c:\>fltmc detach DKTLFSMF c:

    Open in new window

    Right after the command was issued, ActiveSync started working again.  Not sure if this is your issue, but the minifilter drivers may be a good place to look.  

    Good luck,
