No recurring birthday appointment is created for contact

[curchk]

Hi all,

when creating a contact using outlook and after entering a birthday, a recurring appointment is created with the subject "Birthday of Firstname Lastname".

Doing exactly the same using ews-api, no birthday appointment will be created. It seems like this is something done by outlook not on the exchange server (or maybe an error in the ews api?).

I'had the idea to use the BirthdayEventEntryId field (found using outlook spy) and create the appointment manually but I don't know how to read/write the field.

Any ideas how to solve the problem?

Thanks, Christoph
