How to fix: Exchange Mail, Contacts, or Calendars may not sync after iOS 4.0 update

After updating to iOS 4.0 you may notice that Exchange ActiveSync Mail, Contacts, or Calendars do not sync, or sync very slowly and even not syncing. Apple has finally come up with a fix for this, Just follow the below steps:
  • 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.
  • To install the profile:
  • Use Safari on your iOS 4 device to download the configuration profile. It may be easiest to read this article with your iPhone or iPod touch and tap the download link there, but you may also email the attachment to another email account on your iOS 4 device, and tap the attachment to open it.
  • Tap Install to install the profile, and enter your passcode if prompted.
  • A warning message will appear because the profile is not signed. Tap Install Now.
  • Tap Done to complete the installation, then power off your device and power it back on.
  • Wait for your Exchange data to finish syncing.
  • After installation, the profile will be listed under Settings > General > Profile.

3GS, iOS4, Exchange 2003
The initial synch after 4.0 update did take a long time, but it synch exchange mail, cal, and contacts. However, for the past two days, Calendar has not been synching.

I installed the Apple fix above and after rebooting the phone and trying to synch, I receive a message on my iphone: Cannot connect to mail server.

The profile is there in my General Settings, Profile, but now, nothing will synch.

Update: On my iphone, I tapped, Settings, General, Profile, and then tapped REMOVE (to remove the fix above.

After re-booting the iphone, everything Synched beautifully.

@ DAN — I think you don’t need to remove the profile, you just need to install the file then you can add the exchange server profile, then your mail will be push to your HS.
Thanks
