[How To] Resolve Active Sync Issues With iOS 4

Users who have upgraded their iPhone to iOS 4 may had reported delays while syncing with Microsoft Exchange.

Symptoms:

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.

Resolution:

To work around this issue, users should install a configuration profile from Apple that increases the amount of time the iOS 4 device will wait for the Exchange Server to respond to its sync requests. For best results, the profile should be installed on as many iOS 4 devices at your company as possible.

Apple has now released a configuration profile update that will resolve this issue. According to a message posted on the Apple Support website, the new configuration profile will provide a larger duration for the Microsoft Exchange server to respond to sync requests and thereby reduces the syncing related iPhone issues.
