Update: I shouldn't need a Help doc to sign in. ----- Today i was told i had to sign in - by clicking a button labeled "sign out". I did, but now my exchange connections somehow belong to another account so they are deleted. Sign in again and now my password has expired so i have to generate a new password. Forcing users to change passwords is a 90s technique. I go back to the app and i have to click the Sign Out button again. But how do i sign in? It's buried a couple of levels down.
