Past Date Occurrences discarding when updating recurring series RRS feed

  • Question

  • Hi All,

    I am using EWS Managed API to retrieve and update appointments from/to exchange server. I have created one recurrence series appointment.

    Let me walk through this logic with an example. In this example I assume that today’s date is 15<sup>th </sup>JUly 2015.

    I created a series with

    Start Date: 14<sup>th</sup> July 2015 

    Pattern time: 10:00 AM – 11:00 AM Pattern Type: Daily (Recur every one day) and Occurrence count = 5;

    In this case i am getting Recurrence start date from exchange server is:14th July 2015 and Occurrence count = 5.

    after creating series i have updated above series with Pattern Type: Daily(Recur every two days).

    In this case i am getting recurrence series start date from Exchange server is: 15th July and Occurrence count = 4.

    So we are missing one occurrence.

    If we do same operation through outlook it is giving occurrence count  = 5 and recurrence start date is:14th July 2015.(Correct Data).

    Any help would be appreciated.

    Thanks

    I am using this code to update recurrence appointment:

    appointment.Update(ConflictResolutionMode.AutoResolve,SendInvitationsOrCancellationsMode.SendToAll);

    Thanks
