Find out if a specific list of email addresses are Team owners and of what Teams

I got the result I wanted. It might not be pretty but it works.

#Start here and change role to "Member" if want member
Connect-AzureAD

Connect-MicrosoftTeams

$Owner = 'name@yourorg.com'

$Groups = Get-AzureADUser -ObjectId $Owner | Get-AzureADUserMembership | Where-Object {$_.ObjectType -eq 'Group'}
$Results = $Groups | ForEach-Object {
  $TeamID = $_.ObjectID
  $TeamMembers = Get-TeamUser -GroupId $TeamID
  $IsOwner = $TeamMembers | Where-Object { $_.User -eq $Owner -and $_.Role -eq "Owner"}
  if ($IsOwner) {
    try {
      Get-Team -GroupID $TeamID | Select-Object -Property DisplayName, Description, Visibility, MailNickName, Classification
    }
    catch
    {}
  }
}

if (-not($Results))
{
  Write-Host "$Owner isn’t an owner/member of any Microsoft Team (depending on role you select)"
} Else {
  Write-Host $Owner
  $Results
}
