Hi All,

we are developing a sample calendar application using ews managed api. We were using IcalUid of an appointment to differentiate other appointments. I am facing one problem when updating specific occurrence of an recurrence series appointment, it is giving different ICalUid for that recurrence so we are unable to associate this changed occurrence with series.

Is there any other Id that is common for any appointment or series(including specific occurrences)?

Can we use ConversationId to differentiate appointments? Please suggest me.

Thanks

Naresh
