Problem
Logging into a cloud application fails. The account being used to automatically login is incorrect but the option to pick a different account is never given.
Solution
Go to this URL and it will sign out (logout) of the current account https://login.microsoftonline.com/logout.srf
This issue may occur when multiple cloud accounts are being used from the same computer.
