HI Just new to the forums.
I have an odd problem syncing my calendar to my iPhone via itunes. Not all apointments will sync. They all appear to be birthdays or anniversaries. They are all recurrent but recurrent work appointments even far into the future will sync without issue. I have deleted and re-created some of the appointments that won't sync in outlook but they won't sync to my iphone (or ipod touch). Any ideas from you fine folk on the forum would be most appreciated.

iPhone 4 32gb, iOS 4, vista pc

    If you go into the Calendar function on the iPhone and hit the "Calenders" button in the upper left corner it will show you which Calendar(s) it beleives are sync-ed.

    Starting with OS4.x (I think) there is now an "internal" Calender kept on the iphone that is called "Birthdays" and pulls birthdays and anniversaries from your contact records and puts them on the calender. So that is probably where the birthdays are comming from (Not from Outlook).

    If there is a second calendar listed that would be the one that is from Outlook.

    I can't help after that... sorry... my calendar isn't sync-ing either at the moment..........

    The "birthdays"calendar was empty but I've solved the problem. The birthdays had a end date to them. But when I changed them to not having an end date they synced. Not sure why that should make a difference but it does! So problem solved.

    Craig:

    Very odd - what kind of system are you running?
    Mac or PC?

    When I first got my iPhone 3Gs about 18 months ago I was having trouble with the sync-ing of calendars and found that events that DID repeat "forever" were the problem. After changing them to only repeat for (say) one year's worth of time (weekly meetings) or about 10 years (annual events) everything worked OK.
    It appeared that if there were too many entries that the sync. broke. For example I have one uncle born in 1912 (yeah he's seen a few things in his life...) and his birthday would not sync at all until I lied and said he was born in 1972 (other dates might have worked also I just lost motiviation for trying to pin-point the problem -- I had a support case open with Apple but they were never able to explain the behavior .... just that (after I figured it out) "ummm yeah, that's the way it works" ....

    Thanks for your reply, I also am running Vista/Outlook 2007, and could only get the birthdays to sync. (initially - this was back with iTunes 9.x and iOS 3.1x) if I changed the events to NOT repeat forever.... maybe Apple fixed that bug...
