Troubleshooting SSMS Error: 15517

If you meet with the same error as me in SSMS 2016.

Error:

“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 (Microsoft SQL Server, Error: 15517)”

Solution:

use [databasename]
GO
EXEC sp_changedbowner 'sa'
GO

Hope this solution can help you.
