I don't even know where to start with this. Will try iTunes and iPhone forums too. Don't know if this problem is caused by Outlook, iTunes or the iPhone.



I have a new iPhone and just recently discovered that the Calendar is not updating, probably since the first time I synced. And even then it was using old calendar data which doesn't currently show up in Outlook. (Contacts sync perfectly.) Applecare took me through their 1st and 2nd-level support scripts and said they couldn't do anything more. They suggested possible corruption of outlook.pst.

One glaring example: I used to have 3 calendars in Outlook: "Bridge", "Calendar" and "Others". I recently deleted all but the one called Calendar, but all 3 still show up in iTunes, even though I've uninstalled/reinstalled iTunes twice. Only "Calendar" shows up on the iPhone, but it has old data. I think the data it's displaying has not been refreshed since 9/23/11, when I moved the outlook.pst file to a location in My Documents for easier backup, but that doesn't really make sense since the Contacts update just fine. (I've had an iPad for about a year, and it's behaving the same as the iPhone now; the Calendar used to update properly.) Another possible clue: the iPhone shows two instances of one particular recurring appointment. I don't recall ever having two instances of it in Outlook and wonder if that could be the problem. I removed it altogether from Outlook and that didn't help.

I've done extensive testing with a new Windows user account and Outlook, and the calendar syncing seems to work fine. I've Googled "iPhone calendar won't update" and similar and haven't found anything that works for my situation.

I'm running Office 2003 on Windows XP. I do NOT use Outlook for mail.

I'm beginning to suspect corruption in outlook.pst as the culprit. Would appreciate it if anyone who's had this experience could respond, or if anyone can recommend one of the outlook.pst repair programs.
