I had a outlook calendar and I tried to import that calendar to WSS v3
site. As a first step, I successfully exported the contents from
Outlook 2003 calendar to Excel. Then as a second step, I tried to
create a "Import Spreadsheet" in WSS v3 and I failed. After this
failure, none of my other calendars work in any subsite. I tested all
this in my development server. But for some reason, my production site
calendars are also not working after this import/export. Your time and
reply will be a great help for me.
