Users who have upgraded their iPhones to iOS 4 may have experienced delays while syncing with Microsoft Exchange.

These users may notice that applications like Exchange ActiveSync Mail, Contacts and Calendar take an inordinate amount of time while connecting to the server or while syncing data.

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.

If you are among the users facing delays while syncing with Microsoft Exchange, you may follow these steps below to resolve the issue. The instructions involve downloading file components to your iPhone. It is therefore a good idea to visit this page from your iPhone or iPod Touch.

Step 1: If you are reading this from the iOS 4 device, click here to download the configuration profile to your iDevice. Alternately, you can also email the file as an attachment and access it from your iPhone or iPod Touch.

Step 2: You will now be taken to the 'Install Profile' page. Click 'Install' to initiate the download. Enter passcode if prompted

Step 3: Apple will display a warning message to notify that the profile is not signed. Tap 'Install Now'

Step 4:  Once the download is complete, click 'Done' to complete the download process

Step 5: Switch off your iPhone and then reboot. The installed configuration profile may now be viewed on Settings -> General -> Profile.

Microsoft Exchange will now initiate the syncing process. This process should resolve the sync issues that you were observing with Exchange. If you have faced problems on your iDevice, do try to install this update and let us know how it goes in the comments below.
