Wow, Sorry your first post here had to be for a problem... Anyway welcome to 4Winmobile.com.
Unfortunately, once the calendar entries have been removed/deleted from the device, you cannot retrieve them, unless you had already made a backup of them via some other application. If they were never on the pc, you will not find them there now... Unless there is some magic that I am currently unaware of.
The only hope would be that you have mutiple calendars in your Outlook profile.. If so, you can view them in the other calendars... I don't have my hands on an machine with Outlook 2000 on it, but in later versions, when you click on the calendars folder in the left pane, you may see several calendar checkboxes... Make sure you enable them all to see if your data is in any one of them... Of course, this assumes that you have more than one calendar... Hope this helps...
