Microsoft Teams status not updating or changing
Are you unable to update your status in Microsoft Teams? Are you always showing as “Offline” or “Away” in Teams? The troubleshooting recommendations in this article should help you resolve the issue.
Teams changes your status to "Away" if your computer is inactive for five minutes or more. Your Teams status should automatically change when you use your computer again.
If that doesn’t happen, Microsoft recommends waiting at least 3 minutes for Teams to update your status. Reset your status (see the next section) if nothing changes after 5 minutes.
