2858992 - Outlook Server Side Synchronization for Calendar Events

You want to sync calendar events with end date for more than 30 days in the past.

 SAP Cloud for Customer

The server side only allows you to synchronize calendar events from the past 30 days.
This behavior cannot be changed.

The option "Number of Days in the Past to Show", located inside Profiles / Visits affects only the addin behavior, while doing a search for example.
