Hi @Louis Leung
Event Id : 119 Report Server Windows Service has not been granted access to the catalog content
Please refer to this thread: Report Server Windows Service has not been granted access to the catalog content.
Event Id: 28005 An exception occurred while enqueueing a message in the target queue. Error 15517, State 1, Cannot execute as database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission
The easiest way to correct the error is to use ALTER AUTHORIZATION on the databases which have the NULL login match for dbo. It's as simple as:
ALTER AUTHORIZATION ON DATABASE::Example TO sa;
Please refer to this blog for more details: Troubleshooting SQL Server Error 15517.
