    Hi Everyone,

    I've noticed our SBS machine has been running quite slow. w3wp.exe is currently
    using 3.5GB and 40% CPU. Store.exe is using 860MB and 25% CPU. We only have
    about 4 users and have enough disk space. the process behind w3wp.exe is the
    MSExchanceSyncAppPool. Recycling does nothing. If I stop it for a few minutes,
    it all dies down, but when I start it, the problem eventually comes back after a number of hours.

    I read a post somewhere that iDevices running iOS4.0 can cause this. Users have updated with iOS devices.
    Does anyone else know where to start on it? Thanks

    If I stop the app pool and then start it again, w3wp (MSExchangeSyncAppPool starts at around 281MB and 0% CPU.

    Thanks
