Instructions were written for Outlook 2003. Instructions for other programs or versions may differ and The Den can not offer instructions for those. The files should work; just look instructions for Importing CSV files.
1. Open Outlook. Save the file to Desktop (or somewhere else where you know it will be).
2. Go to File -> Import and Export. A new window should open; select "Import from another program or file"; hit next.
3. Select "Comma Seperated Values (Windows)" from the list and hit next.
4. Browse and select the CSV file you saved. Select "Replace duplicates with items imported"; hit next.
5. Select "Calendar" and hit next.
6. Click the check mark next to "Import 'FileName.csv' into folder: Calendar". You should not have to doing anything with the Map Custom button unless you have a different version. Click Finish.
7. All done.
