Get all Teams and channel information using PowerShell

[gcjuw84]

Hi everyone

I'm trying to export a list of all teams in our environment along with their associated channels to CSV.  I have used the script below previously (although this was around a year ago) but am now getting an error saying that Connect-PnPGraph is not recognised.

I'm not sure what's changed and I can't seem to find any documentation on how I can resolve this issue?  I've updated my PnP PowerShell cmdlets but the issue still occurs.  The script I'm using is below and I'd really appreciate any help anyone can give.  Alternatively, if there is another way I can get this information exported I'd be really interested.

Thanks in advance.

function Export-TeamsList
{
param (
$ExportPath
)
process{
Connect-PnPMicrosoftGraph -Scopes "Group.Read.All","User.ReadBasic.All"
$accesstoken =Get-PnPAccessToken
$group = Invoke-RestMethod -Headers @{Authorization = "Bearer $accesstoken"} -Uri "https://graph.microsoft.com/v1.0/groups?`$filter=groupTypes/any(c:c+eq+`'Unified`')" -Method Get
$TeamsList = @()
do
{
foreach($value in $group.value)
{
"Group Name: " + $value.displayName + " Group Type: " + $value.groupTypes
if($value.groupTypes -eq "Unified")
{
$id= $value.id
Try
{
$team = Invoke-RestMethod -Headers @{Authorization = "Bearer $accesstoken"} -Uri https://graph.microsoft.com/beta/Groups/$id/channels -Method Get
"Channel count for " + $value.displayName + " is " + $team.value.id.count
}
Catch
{
"Could not get channels for " + $value.displayName + ". " + $_.Exception.Message
$team = $null
}
If($team.value.id.count -ge 1)
{
$Owner = Invoke-RestMethod -Headers @{Authorization = "Bearer $accesstoken"} -Uri https://graph.microsoft.com/v1.0/Groups/$id/owners -Method Get
$Teams = "" | Select "TeamsName","TeamType","Channelcount","ChannelName","Owners"
$Teams.TeamsName = $value.displayname
$Teams.TeamType = $value.visibility
$Teams.ChannelCount = $team.value.id.count
$Teams.ChannelName = $team.value.displayName -join ";"
$Teams.Owners = $Owner.value.userPrincipalName -join ";"
$TeamsList+= $Teams
$Teams=$null
}
}
}
if ($group.'@odata.nextLink' -eq $null )
{
break
}
else
{
$group = Invoke-RestMethod -Headers @{Authorization = "Bearer $accesstoken"} -Uri $group.'@odata.nextLink' -Method Get
}
}while($true);
$TeamsList |Export-csv $ExportPath -NoTypeInformation
}
}
Export-TeamsList -ExportPath "C:\teamslist.csv"

@RealTime_M365 

That's great thanks.  I used the script provided in your second link and added a few lines to also output a count of the channels in each team along with the channel names.

Thanks again for your help.

@gcjuw84 

Can you post the final script.
I am having trouble with exporting the channels with this script.

@Sebastian Di Cecca 

No problem, the final script is below.  Before running the script you need to make sure you run Connect-MicrosoftTeams and Connect-ExchangeOnline.

Any problems let me know.

$AllTeamsInOrg = (Get-Team).GroupID
$TeamList = @()

Write-Output "This may take a little bit of time... Please sit back, relax and enjoy some GIFs inside of Teams!"
Write-Host ""

Foreach ($Team in $AllTeamsInOrg)
{       
        $TeamGUID = $Team.ToString()
        $TeamGroup = Get-UnifiedGroup -identity $Team.ToString()
        $TeamName = (Get-Team | ?{$_.GroupID -eq $Team}).DisplayName
        $TeamOwner = (Get-TeamUser -GroupId $Team | ?{$_.Role -eq 'Owner'}).User
        $TeamUserCount = ((Get-TeamUser -GroupId $Team).UserID).Count
        $TeamGuest = (Get-UnifiedGroupLinks -LinkType Members -identity $Team | ?{$_.Name -match "#EXT#"}).Name
            if ($TeamGuest -eq $null)
            {
                $TeamGuest = "No Guests in Team"
            }
        $TeamChannels = (Get-TeamChannel -GroupId $Team).DisplayName
	$ChannelCount = (Get-TeamChannel -GroupId $Team).ID.Count
        $TeamList = $TeamList + [PSCustomObject]@{TeamName = $TeamName; TeamObjectID = $TeamGUID; TeamOwners = $TeamOwner -join ', '; TeamMemberCount = $TeamUserCount; NoOfChannels = $ChannelCount; ChannelNames = $TeamChannels -join ', '; SharePointSite = $TeamGroup.SharePointSiteURL; AccessType = $TeamGroup.AccessType; TeamGuests = $TeamGuest -join ','}
}

@gcjuw84 

Thanks alot! I'll give it a try!

[#7]

@gcjuw84 

I have used the scrip and it is great!

But I see that it only lists the public channels.

Some way you list the public and private?

thanks

[#8]

@amkaccion1966 

I've just tested this my end and the script seems to show both public and private channels.  The Get-TeamChannel should show all channels regardless of whether they're public or private and this is what's used in the script.

If you go into the Teams Admin Centre and view team details via the Manage Teams can you see private channels for a team that has them there?

[#9]

Is there a place where I can grab dates of "last's", i.i. Last chat message, last user added, last file added, etc.  Our organization implemented Teams with no oversight so there are a lot of orphaned teams.
Thanks!

@gcjuw84 

Thank you for the Script but when I excecute it, I get after about an hour "Access denied"

I did connect-exchangeonline and connect-microsoftteams before.

Also I have the needed Tenant permissions.

Thanks, Philip

Dears,

Thanks for sharing the script and ideas. I am expanding on this and when I try to find if the user is a member or owner of the Team Channels they belong to using Get-TeamChannelUser as described in the documentation, it does not work.
https://docs.microsoft.com/en-us/powershell/module/teams/get-teamchanneluser?view=teams-ps

Do anyone know how to get the information if a user is a member or owner of a Team Channel?

Thanks

$MyTeams = Get-Team -User bob@contoso.com
Foreach ($Team in $MyTeams)
{
Get-TeamChannel -GroupId $Team.GroupId
Get-TeamChannelUser -GroupId $Team.GroupId
}

[#13]

I am looking for this as well. I need powershell to loop through all Teams, report users access level (eg, owner, member or guest) and then loop through all the channels of that team to export users access level of each channel. And do this for each Teams. Anyone have an example?

[#14]

@colynykalphiacom - were you able to do this? I am currently still exploring this as well.

[#15]

After 10 hours of running the script, eventually all I got is:

Write-ErrorMessage : The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.

[#16]

90% of the time, its better to filter on the server side, this might work a little faster, and will give you some feedback:

$TeamList = @()
$i = 0
Write-Host "This may take a little bit of time... Please sit back, relax and enjoy some GIFs inside of Teams!"
