Prepare all related ics files
- Go to calendar and save each relevant event as dedicated ics file (use save as) in one directory
Merge all ics files into one
- open command line
- navigate to the directory where all your ics files are located
- merge them easy together by executing the command copy *.ics all.ics
- Open the merged ics files with your favorite editor
- Ensure BEGIN:VCALENDAR exists only once at the first event
- Remove all other BEGIN:VCALENDAR of other events (use search and replace function)
- Ensure END:VCALENDAR exists only once at the end of the file
- Remove all other END:VCALENDAR of other events (use search and replace function)
- Ensure you have a clean rows between events, without unnecessary space characters:
Fine-tuning of the merged ics before import
If you try to import the ics without fine-tuning, it will not work. Outlook will import only one event. To make it possible, follow the steps below:
Import your final file in your Outlook calendar
- Go to file > open and export > import / export
- select iCalender (ICS) import as action > next
- select your final ics files > import
- select dedicated calendar or just import in your current calendar
