Displaying your screen content to others during a Teams meeting or call for collaboration
Dear Jeff,
The error you see doesn't come from the normal Teams sign‑in page. It usually means the link you're using is outdated or comes from a bookmark, app or third‑party website that relied on an old service.
To use Teams, sign in here: https://teams.cloud.microsoft
To share your screen, join or start a meeting, then select Share in the meeting controls. There isn't a separate URL that starts screen sharing directly. If you're using Teams in a browser, Microsoft Edge or Google Chrome works best for screen sharing.
If you got the link from an app, website or script, could you please share where it came from and the first part of the address? Please remove any IDs, tokens or personal details first.
Once I have these details, I can help you find the right link.
