Microsoft is working with Apple to help it resolve issues with iOS 4, Apple’s latest update to the iPhone OS, and Exchange ActiveSync. Earlier this week Apple released an update to fix some of these issues. See Apple fixes issue with iOS 4 and Exchange ActiveSync.

In a blog post on the Exchange team blog, Microsoft’s Adam Glick confirms the issues users are facing with Apple’s new iPhone 4, and older iPhone devices that have been upgraded to iOS 4. The post lists 3 issues that iOS 4 users been having with EAS:

  1. iOS4 devices causing “heavier than normal load” on Exchange Server
  2. Email, calendar or contacts not syncing
  3. iPhone’s not working with Google Apps over EAS

As Adam states:

We are in contact with Apple’s engineering team and are trying to help them fix this issue.

However, as far as issues with Google Apps are concerned, Google’s responsible for its server-side EAS implementation working correctly, and in this case Google claims it had a server issue.
