6 years ago Hello Sebastian. Just trying to be helpful but i guess you could go on each past occurrence in the series and update it manually.
It's not pretty but i guess it's a solution :)
Hallo,
when I am updating the recurrence object of a master appointment, only appointments in the feature will be updated with this new Recurrence informations (e.g. the interval property). All past occurrences will have its own recurrence series with the old informations (the old interval). So ews is splitting up the series into two series (past occurrences and future occurrences)
When I am updating master informations only affecting properties that are NOT in recurrence object, the whole series will be updated with the new informations like expected without splitting up the series in two part (past occurences and future occurrences).
In my project I need to update the interval of a series for ALL occurences including the past ones (this is also the standard behaviour when updating the master interval via outlook).
Is there any way I can achieve this? Thanks!
