Q&A: why don't new events created on my iPhone show up in Entourage?

I got a question about using Sync Services on Entourage 2008 with an iPhone:

I have trouble synching my iPhone and the calendar feature. For some reason it does not always work very well. Things I write on the phone never make it to my calendar on my Mac. Any thoughts?

Make sure that your iPhone is writing to the correct calendar. For the items to show up in Entourage, the new events that you add to your iPhone must be written to the calendar named "Entourage". To check this, open up iTunes when you have your iPhone connected to it. Then select the your iPhone, and select the "Info" tab. Under "Calendar", select the calendar named "Entourage", and then select to put new events in the "Entourage" calendar.

If you never use iCal, you can take this one step further. Open up iCal. You'll see an Entourage calendar in there, and it has all of your Entourage calendar events in there. iCal also has a couple of default calendars. You can delete those calendars by clicking on them in the "Calendars" list on the left side and hitting delete. Then there won't be any other place for your new events created on your iPhone to go.

If you're interested in the gory technical details of how Entourage syncs with your mobile devices, one of my colleagues wrote an essay about it, which the Entourage MVPs kindly have posted on their site: basics of how Sync Services works.

You can sync your supported mobile device with Entourage 2004 (11.2.3 or later), Entourage 2008, or Entourage for Exchange Web Services. I covered the basics of syncing your device with Entourage in an earlier blog post: Q&A: How do I sync from Entourage to my iPhone?
