You're located in China Mainland and trying to synchronize from Outlook to SAP Cloud for Customer via Server Side Integration, but it doesn't work.
When you try to access the "User Settings" workcenter nothing appears, the screen is all blank.
SAP Cloud For Customer
Server Side Integration uses Google API's to work which are blocked in China Mainland.
This is the standard behavior of the system. The improvement of this behavior is already on the roadmap for future releases of the server side integration.
An alternative option may be to check the SAP Customer Influencer Site to submit an idea.
