OK let me save you an hour of your life. You will need:
- 1 USB cable
- latest copy of iTunes
- Your Outlook (I have 2003), computer and phone.
Based on this slightly out of date article, it’s advised to reset your sync settings first. It was necessary for me. You need to:
- connect your iPhone up with the USB cable
- open iTunes.
- Go Edit and Preferences
- Click the ‘Device’s tab
- In this release of iTunes, there’s a ‘Reset Sync History’ button. Click it and then click ‘OK’
- Now select your iPhone under ‘Devices’ from the column on the left
- Select the ‘Info’ tab on the horizontal menu
- Scroll down to the ‘Calendars’ heading
- Tick the box ‘Sync calendars with Outlook’
- Click ‘apply’ at the bottom right.
- Now click the ‘Sync’ button where the ‘apply button was.
And now you’re done! Don’t get sucked into buying stuff you don’t need. And thankfully you don’t need to sync every single option (e.g. your music and mail) you can sync only what you want. No need to buy additional software or MobileMe or anything. It’s all sorted.
