iPhone deleted my entire Outlook calendar

I synced my iPhone with my Outlook for the first time and all my calendar events (all are work-related) have been deleted from my computer! The ones from the past that I accepted from my iPhone's outlook are still on the phone. I can't figure out how to sync the iPhone to the Outlook. I do not have Google Calendar.

I have tried Edit -> Preferences -> Devices -> Reset Sync History, but I think that only applies to resetting the device info, not the computer.

My iTunes settings are such that devices do not automatically sync. In iTunes under my iPhone and Info, I have it to sync Outlook -> All Calendars (as there is only one on this comp).

Please help! I need all my calendars to be available at all times.

Thank you!!

Glad to hear it helped.

hello, I think I have the same problem. i wanted to bring my gmail calendar to outlook and as I already have synced my iphone calendar with gmail, I decided to start itunes, connect my iphone, go to the info tab and sync my calendar to outlook. I did that and hit the Sync buttton but there are absolutely no events in my Outlook calendar. I tried the outlook /resetfolders suggestion, but other than this opening my Outlook (upon hitting the Enter button on my keyboard), it was of little help.

You might want to directly export your iphone calendar into iCalendar format on your computer (ICS file). Once you have the ICS file, import it to Outlook via the Import/Export wizard as described here:

How to import iPhone calendar to Outlook?

Hello, I have had the same problem. I set my iPhone up and all my Outlook appointments were on the phone and laptop, then 30 minutes later they vanished from the phone and laptop.
I have tried the eHow link from mach04 but when I click run and search for "calendar/reminders" i get a message saying "command line argument is not valid. Verify the switch you are using."
Any help will be much appreciated.

It seems that you have mistyped.

when I click run and search for "calendar/reminders" i get a message saying "command line argument is not valid.

You need to type outlook /cleanreminders after the Run is displayed, then open Run again and type outlook /resetfolders then relaunch Outlook.
