With Teams the Admin center does not currently give any information on when a Team was created. The PowerShell script below will list all the Teams and the date when they were created.
# List All Teams and creation date
Import-Module MSOnline
Import-Module MicrosoftTeams
[string]$username = "[email protected]"
$cred = New-Object System.Management.Automation.PSCredential
# Connect to Exchange powershell
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $cred -Authentication Basic -AllowRedirection
Import-PSSession $session
# Connect to Teams powershell
Connect-MicrosoftTeams
Write-Host "Getting Teams..."
$Teams = Get-Team
$teamdata = @()
Write-Host "Getting UnifiedGroup data..."
foreach($Team in $Teams)
{
$TeamUG = Get-UnifiedGroup -Identity $Team.GroupId
$teamdata += @(
[pscustomobject]@{
DisplayName = $Team.DisplayName
CreationDate = $TeamUG.WhenCreated
}
)
}
# display results
$teamdata | sort displayname
