I've recently bought a Surface Pro 3 and initially set it up with a user connected to a mail account. For this purpose I creadted an account on outlook.com. After that I created a local account and used that. Both accounts were working. Now I need to log on with my email account again, but Windows keeps telling me that the credentials aren't right. If I use the same e-mailaddress and password to directly log on via the Internet to outlook.com, it works perfectly. When I was logged on with my mail account I installed SQL Server. Since I could't add the local account as administrator, since it didn't exist yet, I now can't open SQL Server. Who can help me?
