Hi Karen,
Greetings.
Thank you for raising your concern in this community.
There are different links that you can share in teams
You can share a link to access a team, or a channel. For both the process is the same
In the team or channel, click more options (the 3 dotes) and get link to team. Which you can copy and share.
There is also the option to copy the Files link. Also after creating a meeting, you have to option to share the link to the meeting.
If you just want he email address of the team, you can get by clicking more options on the top right followed by get email address. If you don't find it you can ask the owner of the team if the email address was removed or if there is any restriction applied.
In the eventuality that this is not enough, please let me know if you need further assistance.
PS: Any Questions related to M365 Business is welcomed in this forum.
