Starting-point is an Excel-List containing the names and dates of birth for a lot of person. Those should be imported to Outlook as event series (yearly reoccurring event).

Outlooks CSV-import doesn't supports reoccurring events. 
The best solution would allow to import the list even again, when someone is added or removed and then events are updated.

I had a look to import the list to a new, separate calendar and show them in list-view but wasn't able to modify all imported events to become yearly reoccurring.

Maybe csv-import is not the best solution?

Does anyone has an idea or eventually a working solution?
