Thank you for getting back to me and for sharing the screenshot.
From what I can see in the image, you’re accessing Teams via a teams.live.com link, which usually means you’re signed in with a personal Microsoft account. At the same time, your question is posted under the Microsoft Teams for Business tag, which is mainly intended for work or school accounts. Because of that, there’s been a bit of confusion around the account type involved here.
Just to gently set expectations, my knowledge and hands-on experience are more focused on configuring and supporting Microsoft Teams for Business environments. Because of that, scenarios involving personal accounts may fall slightly outside what I can confidently troubleshoot in detail.
That said, I’d really encourage you to review the answer and the reference article shared earlier by Ruwim.B, as their guidance is much better aligned with personal account use cases and may help point you in the right direction.
If you try that and it still doesn’t resolve the issue, the best next step would be to post your question again and choose a tag that’s more specific to Microsoft Teams Free. That way, your question will reach the right group of experts and community members who have hands-on experience with personal account behavior and limitations.
