Lost entries in Outlook 2000 Calendar

[BarryS]

I normally don't ask MS software issues here, but I was hoping someone might have an answer. I was using MS Outlook 2000 on my desktop earlier this morning, but was unable to log on to our Exchange Server to get my email as usual. IS got the server back online but when I rebooted my PC, all my Calendar entries were missing. All of my other folders in Outlook are okay. Any idea what happened and is it recoverable? What is the filename for the calendar folder anyway?

Thanks,
