In this guide, you'll use the Microsoft Graph PowerShell SDK to perform some basic tasks. If you haven't already, install the SDK before following this guide.
The SDK contains two modules, Microsoft.Graph and Microsoft.Graph.Beta that call the Microsoft Graph REST API v1.0 and Microsoft Graph REST API beta, respectively. Cmdlets are available for the module that is installed.
The PowerShell SDK supports two types of authentication: delegated access, and app-only access. In this guide, you'll use delegated access to sign in as a user, grant consent to the SDK to act on your behalf, and call the Microsoft Graph.
For details on using app-only access for unattended scenarios, see Use app-only authentication with the Microsoft Graph PowerShell SDK.
Each API in the Microsoft Graph is protected by one or more permission scopes. The user logging in must consent to one of the required scopes for the APIs you plan to use. In this example, we'll use the following APIs.
- List users to find the user ID of the logged-in user.
- List joinedTeams to get the Teams the user is a member of.
- List channels to get the channels in a Team.
- Send message to send a message to a Team's channel.
The User.Read.All
permission scope will enable the first two calls, and the Group.ReadWrite.All
scope will enable the rest. These permissions require an account with the Application Administrator or Cloud Application Administrator role to grant consent. For more information, see Microsoft Entra built-in roles.
The Find-MgGraphCommand
cmdlet can be used to discover the required permissions for another cmdlet. For example, to see all permissions that can be used to call Get-MgUser
, run;
Find-MgGraphCommand -command Get-MgUser | Select -First 1 -ExpandProperty Permissions
Name IsAdmin Description FullDescription
---- ------- ----------- ---------------
Directory.Read.All True Read directory data Allows the app to read data in your organization's directory.
Directory.ReadWrite.All True Read and write directory data Allows the app to read and write data in your organization's directory, such as other users, groups. It does not allow the app to delete users or groups, or reset user passwords.
User.Read.All True Read all users' full profiles Allows the app to read the full set of profile properties, reports, and managers of other users in your organization, on your behalf.
User.ReadBasic.All False Read all users' basic profiles Allows the app to read a basic set of profile properties of other users in your organization on your behalf. Includes display name, first and last name, email address and photo.
User.ReadWrite.All True Read and write all users' full profiles Allows the app to read and write the full set of profile properties, reports, and managers of other users in your organization, on your behalf.
This output has been shortened for readability.
For more information on using this cmdlet, see Using Find-MgGraphCommand.
Use the Connect-MgGraph
command to sign in with the required scopes. You'll need to sign in with an admin account to consent to the required scopes.
Connect-MgGraph -Scopes "User.Read.All","Group.ReadWrite.All"
The command prompts you to go to a web page to sign in with your credentials. Once you've done that, the command indicates success with a Welcome To Microsoft Graph!
message. You only need to sign in once per session.
Tip
You can add additional permissions by repeating the Connect-MgGraph
command with the new permission scopes.
Now that you're signed in, you can start making calls to Microsoft Graph.
[!INCLUDE aad-advanced-queries-note]
In this section, you'll locate the signed-in user and get their user Id. You'll need the user Id as a parameter to the other commands you'll run later. Start by running the following command.
Get-MgUser
This command outputs a listing of users in your Microsoft 365 organization.
Id DisplayName Mail UserPrincipalName

You can use an OData filter to help locate the specific user you want. Run the following command, replacing Megan Bowen
with the display name of the user you signed in with.
$user = Get-MgUser -Filter "displayName eq 'Megan Bowen'"
Verify that worked by entering the following.
$user.DisplayName
Now use the user's Id as a parameter to the Get-MgUserJoinedTeam
command.
Get-MgUserJoinedTeam -UserId $user.Id
Just like the Get-MgUser
command, this command gives a list of teams. Select one of the user's joined teams and copy its Id
, to use in the next command.
$team = Get-MgTeam -TeamId ID_FROM_PREVIOUS_STEP
Now use the team's Id as a parameter to the Get-MgTeamChannel
command, following a similar pattern of listing all channels, then filtering the list to get the specific channel you want.
Get-MgTeamChannel -TeamId $team.Id
$channel = Get-MgTeamChannel -TeamId ID_FROM_PREVIOUS_STEP -Filter "displayName eq 'General'"
Now that you have both the Team Id and the channel Id, you can post a message to the channel. Use the following command to send the message.
New-MgTeamChannelMessage -TeamId $team.Id -ChannelId $channel.Id -Body @{ Content="Hello World" }
This command differs from the previous commands you used. Instead of querying data, it's creating something. In Microsoft Graph, this command translates to an HTTP POST
, and it requires an object in the body of that post. In this case, the object is a chatMessage. The -Body
parameter to the command maps to the body
property on chatMessage
. Other properties are mapped in a similar way, so you can change the message you send. For example, to send an urgent message use the following command.
New-MgTeamChannelMessage -TeamId $team.Id -ChannelId $channel.Id -Body @{ Content="Hello World" } -Importance "urgent"
Use the Disconnect-MgGraph
command to sign out.
