I keep Microsoft Teams open at all times. Sometimes when I have Teams minimized, I will show as offline to my coworkers. I won't receive any notifications of messages from any Teams and/or Chats, even if I am @'d. If I open the Teams window from my task-bar, it will show the offline symbol for everyone briefly, before eventually showing everyone's status correctly (and mine to everyone else).
My Teams notification settings are setup as attached:
@MitchellJ If you are offline then the client isn't connecting to the service, I would suggest looking at network components. Maybe something in your network firewall is preventing Teams staying connected?
I am experiencing this exact problem. Any time I minimize my Teams window I go offline. Often I will receive an email (yes, an email) from Microsoft letting me know that someone sent me a message on Teams, which prompts me to maximize the Teams window to receive the messages... seems rather insane to me.
This assuredly is not a network problem since I can repeatedly duplicate the problem simply by minimizing and maximizing the Teams window. Hopefully MS will address this problem with an update.
My W10 is 100% up to date as are all of my other apps and components.
