Getting a lot of error messages in event viewer about SQL Server. Error message is as follows:
An exception occurred while enqueueing a message in the target queue. Error: 15517, State: 1. Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission.
All databases are owned by same username except for the system databases which are set as SA as owner and I cannot change that ownership. Any ideas on how to resolve this error message?
