What the Available Status Actually Means
The green Available status — represented by a green circle with a white checkmark — is Microsoft Teams' strongest "I'm here" signal. It tells colleagues you're at your computer and likely to respond quickly. It's the status everyone wants, the one that says "I'm working" even when the work happens in another application.
From a presence-service perspective, Available means: "At least one of this user's Teams clients has signalled activity within the recent window." It's a positive statement — not the absence of an Away signal, but an active assertion that the user is engaged.
From a colleague's perspective, it's a green light. Messages get sent. Channels get tagged. Meetings get scheduled with confidence that the person on the receiving end is going to see them.
How Teams Determines You're Available
Teams sets your status to Available based on signals from your registered clients:
- Mouse or keyboard input detected by the Teams desktop client (system-wide on macOS/Windows)
- Browser-tab focus and input on the Teams web client
- Active participation in a Teams call, meeting, or screen share
- Recent messages sent in any channel or chat
- Manual selection to Available (briefly — Teams will override if signals don't follow)
Any one of these is enough to keep you Available. The presence service uses the most-active client at any moment — so if you have desktop and mobile both running, mobile-only activity will keep you Available even if your desktop is idle.
The Inactivity Window
Available isn't permanent. Teams expects to see fresh activity signals roughly every 5 minutes. If no signals arrive within that window, you transition to Away — the inactivity timer that drives most of the "Why am I yellow again?" frustration on Teams.
This is the structural reason it's hard to "stay green" on Teams: the system was designed to actively verify your presence on a short cycle, not to honour a one-time "I'm here" declaration.
What Others See When You're Available
The green check icon appears in five places:
- Next to your name in chat lists and channel sidebars
- On your avatar in channel posts and message replies
- In the Members panel of any team or channel
- In Outlook integrations, SharePoint, and Microsoft 365 Groups (Teams' presence service is shared)
- In search results and people-picker UIs everywhere Teams is integrated
Colleagues' UIs typically default to "Available users only" filters in some search contexts. Being Available is also what populates the "Suggested participants" in new meeting invites. The green dot has a substantial effect on whether you're seen and surfaced.
Can You Force Available Permanently?
Not from inside Teams. Manual Available selections last briefly, but Microsoft's presence service ultimately trusts client activity signals over user preference. Set yourself Available, walk away for ten minutes, and you'll find yourself flipped back to Away.
This is documented behaviour, not a bug. The presence service is designed to reflect real activity. To stay Available indefinitely without manual gymnastics or hardware tricks, you need a real signal — which is exactly what cloud-based presence services like Stay Green On Teams provide.
How Stay Green On Teams Maintains Available
Rather than overriding Teams' presence at the UI layer, Stay Green On Teams works at the API layer — the same layer Microsoft's own Teams clients use to signal activity. Our cloud workers connect to Microsoft's presence infrastructure using your captured session credentials and signal "this client is active" continuously while you're within your scheduled hours.
From Microsoft's perspective, your account has another active Teams client connected at all times. That's enough — the presence service treats your status as Available, the same way it would if you had Teams open on a second computer somewhere.
You can close your laptop, leave your phone in airplane mode, and disappear for hours. Your status stays Available because the cloud worker is doing what an active Teams client would do — minus the requirement that you keep a device awake.
Frequently Asked Questions
What does the green check icon mean in Microsoft Teams?
The green check indicates Available — Teams detects you're actively using one of your registered clients. Set automatically by mouse, keyboard, or in-call activity within the recent 5-minute window.
Can I manually set my Teams status to Available?
Yes, but it's not permanent. Right-click your avatar and select Available. Teams will hold the setting briefly, but will eventually revert to Away if it doesn't see fresh activity signals from any of your clients.
Why doesn't my Available status stay on when I set it manually?
Microsoft's presence service treats manual Available as a preference, not an override. If no activity follows within roughly 5 minutes, Teams reverts you to Away. The design favours accurate presence over user choice.
Does being in a Teams call show me as Available or Busy?
Being in a Teams meeting or call shows you as Busy (red square), not Available. The two are different states — Available means 'free to chat,' Busy means 'engaged in a meeting right now.'
How does Stay Green On Teams keep my status Available?
Stay Green On Teams runs a cloud worker that maintains a Teams presence connection using your own session credentials. From Microsoft's perspective, you have another active Teams client connected continuously. Your status stays Available regardless of whether your local devices are on.
Will Stay Green On Teams keep me Available while I'm in a Zoom meeting?
Yes. Stay Green On Teams maintains your Available state independently of any meeting platform. Teams' built-in calendar integration may briefly show you as Busy when you're scheduled in a Teams meeting, but third-party calls (Zoom, Google Meet) don't affect your Available status either way.
