"Something went wrong" page with error DatabaseNotFoundException [FIXED]
When you try to login to your mailbox that connects to an Exchange Server, you might receive a "Something went wrong" page, with error DatabaseNotFoundException.
To resolve this issue, login to your account using this link: http://outlook.live.com/OWA
If you still get the error, add an Outlook.com alias to your account, (if you don’t already have one) and use that alias as your primary alias.
