What the sign-out messages mean
A small number of panels, each with a different cause. Only two of them mean something is wrong with the account.
Being signed out unexpectedly produces one of a small number of panels, and the title on it says which. Most mean nothing is wrong.
Two of them are about the account rather than the session, and those are the two worth acting on. The rest are ordinary and signing back in is the whole remedy.
An administrator ending your session deliberately looks identical to an ordinary timeout, so the panel cannot tell you that happened.
The message underneath is what separates them, because two very different situations share the same title.
| Title | Message | What it means |
|---|---|---|
| Session Expired | “Your session has expired due to inactivity. Redirecting to login…” | Idle too long. Nothing is wrong |
| Session Expired | “You are no longer signed in. Redirecting to login…” | The session ended. This covers being signed out because the account signed in elsewhere, and an administrator ending the session deliberately |
| Account Disabled | “Your account has been disabled. Please contact your administrator.” | The account itself is disabled. Signing in again will not help |
| Account Not Found | “Your account no longer exists. Please contact your administrator.” | The account has been removed |
| Authentication Error | “Unable to verify your account. Redirecting to login…” | The check against Microsoft did not complete. Usually temporary |
Good to know
Several different situations produce a Session Expired title, and the message underneath separates only some of them.
A Session Expired panel that comes back every time you sign in means the account rather than the session. Some account problems arrive wearing this title rather than their own, so repetition is the signal rather than the wording.
Account Disabled and Account Not Found say so directly. Both mean the account rather than the session, and both keep happening until somebody changes the account.
