Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Teams can be used with or without a Msft 365 subscription.
If you don't have the app yet, download it from here: [https://www.microsoft.com/microsoft-teams/download-app](https://www.microsoft.com/microsoft-teams/download-app
)
Just sign into your Microsoft account to use it.
As for inviting people without showing your email address, instead of inviting them directly, create the meeting and then share the meeting link via other methods.
However, I want to point out -
If the other user signs into their Microsoft account to join your meeting, they can still see your contact card details. Unless you do the following first.
Go to Teams settings > Privacy > Manage your profile.
Make sure all email alias is set to "hide". This way when they hover over your username in the meeting, they won't see your email address.
