1. Sync Your Entourage Contacts with Address Book

To get your Entourage contacts into Address Book, launch Entourage and go to Entourage > Preferences. In the left pane under General Preferences, select Sync Services. Then select the checkbox for “Synchronize contacts with Address Book and .Mac.” If you have multiple Entourage address books, select the one you want to sync in the pull-down menu.

After you click OK, you are asked about which direction you want to sync. Entourage confusingly uses the term Sync Services -- just replace those two words in your head with Address Book (and .Mac). Select the first option if you want to replace your Address Book contacts with your Entourage contacts. Select the second option if you want to replace your Entourage contacts with your Address Book contacts. The third option merges your Entourage and Address Book contacts. Click OK.

2. Sync your Entourage Calendar with iCal

Syncing your Entourage calendar to iCal is similar to syncing your contacts. Go to Entourage > Preferences, and in the left pane under General Preferences, select Sync Services. Select the checkbox next to “Synchronize events and tasks with iCal and .Mac.” If you have multiple Entourage calendars, select the one you want to sync in the pull-down menu.

Just as in Step 1, you are asked about which direction you want to sync. In this case, Sync Services is code for iCal (and .Mac). The first option replaces your iCal calendar with your Entourage calendar. The second option replaces your Entourage calendar with your iCal calendar. The third option merges the two. Click OK.

If you launch iCal, you’ll notice that there’s a new calendar called Entourage. Events need to be entered into this calendar in order for iCal and Entourage to sync. If you create another calendar in iCal, Entourage won’t import the events in that calendar.

3. Sync Your iPhone

In iTunes, select your iPhone under Devices, and then click the Info tab. Check the Sync Address Book Contacts box to bring your contacts into your iPhone. Check Sync iCal Calendars to import your events into your iPhone. If you want, you can also choose to import only select groups and calendars.
