What are the limitations of Office 365 API?

Office 365 APIs have some limitations because of the bugs in their APIs.

• For Recurring Events that are created with no end date, Vtiger syncs events based on these conditions.
  • If End Date < 31-12-2100, then only 500 events will be synced.
  • If End Date > 31-12-2100, then based on the recurring condition events, will be synced until the year 2100.
• The Birthday field is not synced because the date returned from Office 365 is always one day more.
• Contacts sync does not support Group Level sync as Office 365 has a bug wherein all the newly added contacts go to the default contacts group instead of the group that was selected for sync.
• Field Mapping cannot be changed; it is fixed.
