Exchange client behavior
If a recurring meeting is created, Planon ProCenter will send an accept notification for the whole series and will send additional confirmation mails including a link to Planon Self-Service Per occurrence.
When a single occurrence is declined, by default the occurrence date is marked as exceptions in Exchange. If you move or change the duration of the meeting on the same day:
Outlook® Web Access
The meeting will not act as a recurring meeting. None of the calendar item's exceptions will be updated. They will all remain as exceptions.
Outlook®
The meeting acts as a recurring meeting. All calendar items are updated to the new time/duration. The message that all single exceptions are lost and are recurrent again will be displayed.
