Error: Either the user does not have access to the database, or the database does not exist

Connect to the Analysis Services

Select the Server name and Connect (with the Admin Account) 

Right Click on Server and click Properties

Click the Security and Click Add and add the user which you need and click ok. 

Now try to access the Cube Excel file and the “Error: Either the user does not have access to the database, or the database does not exist” will be gone now. 

Thanks
