A recent Apple support note offers help for the times when iOS 4 slows way, way down during syncs with Exchange ActiveSync Mail, Contacts, and Calendars. The problem may also bring performance problems for Exchange servers.

Immediately after updating to iOS 4, some users may notice that Exchange ActiveSync Mail, Contacts, or Calendars do not sync, or sync very slowly. In addition, some Exchange Server administrators may notice their servers running slowly.

Apple says the work around for this issue is a new configuration profile that increases the time the iPhones will wait for the Exchange Server to respond to a sync request.

For best results, the profile should be installed on as many iOS 4 devices at your company as possible.

Updated Sunday, July 11: This fix appears to have mixed results, according to the MacWindows blog.

  • RE: After the iOS 4 upgrade: Fix for slowing Exchange sync

    This is great how does one push this to users OTA without having to physically touch every iOS4? <br><br>Seems you can either email or host on a website but you still rely on users to actually install it, anyone in IT knows the success rate that will be. Much easier to disable the iOS4 from connecting to Exchange until Apple fixes their product.<br><br>Maybe someday Apple will actually test their products prior to releasing them, share release notes etc.

    • Or....

      They could leave Exchange connectivity to third party app providers. But then, that would actually make sense.

        @jasonp@... That doesn't solve the problem. We use a third party provider for Exchange and their servers were hard hit by iPhone users resulting in lost connections from our desktop clients (Outlook, Entourage). As the culprit was outted (iOS 4 ActiveSync profile), they sent out an email noting what had been ferreted out and a link to an Apple support page which has iPhone users change their profile.

        So no, third party provider doesn't solve the problem.

  • No issues here

    Calendars and mail syncs perfectly!

    • Nor here as well...

      But, we're running BES and nothing but Blackberry handhelds, so we've not had any "reception" issues either.

  • Why things that work now don't work? If it ain't broke...

    Why something that works now doesn't work? It seems to me that: a) it is related to the connectivity issues - antenna? b) the OS changed something fundamental, and the Activesync had to be re-written, bringing in problems, or it is the same Activesync under new dynamics...

    My iOS4 upgrade made my 3G phone VERY slow but only for 1 day. Weird. Now it just zips along. No other updates. Just seems to have 'fixed' itself!

    Love Apple Products! Yummy!
