Thanks for the reply. I got no warning at all. It just went blank. I checked to see if the memory was full, and it was. I restarted the phone and that cleared up about 22 megabytes of space. My information is still in Outlook, but when I synced the phone with Outlook, it only copied calendar dates from today forward. It no longer has the "history" part of the calendar, which I would like to restore as well.
