Connect-MgGraph -NoWelcome: hide the Welcome to Microsoft Graph! message

Connect-MgGraph -NoWelcome connects to Microsoft Graph PowerShell without printing the welcome message. Without it, every successful connection writes "Welcome to Microsoft Graph!" followed by links to the SDK documentation and the note "NOTE: You can use the -NoWelcome parameter to suppress this message." The reference describes the switch simply as "Hides the welcome message." It is meant for scripts, scheduled jobs and logs.

Connect-MgGraph -Scopes "User.Read.All" -NoWelcome
Connect-MgGraph -ClientId $appId -TenantId $tenantId -CertificateThumbprint $thumb -NoWelcome
Get-MgContext | Select-Object Account, TenantId, Scopes, AuthType

The switch in the module

-NoWelcome is a switch parameter available in every parameter set of the authentication cmdlet (interactive, device code, certificate, secret, managed identity, access token), so it combines with any sign-in method. Because it is a switch with default False, -NoWelcome alone is enough; unlike Exchange's -ShowBanner, no colon syntax is needed. Checked offline in Windows PowerShell 5.1 with Microsoft.Graph.Authentication 2.41.2, by listing the module's cmdlets that have it:

Import-Module Microsoft.Graph.Authentication
(Get-Module Microsoft.Graph.Authentication).ExportedCommands.Values |
  Where-Object { $_.Parameters.ContainsKey('NoWelcome') } | ForEach-Object {
    $p = $_.Parameters['NoWelcome']
    '{0}: {1}, in all parameter sets: {2}' -f $_.Name, $p.ParameterType.Name, ($p.ParameterSets.Keys -contains '__AllParameterSets')
  }

Connect-MgGraph: SwitchParameter, in all parameter sets: True
Connect-Graph: SwitchParameter, in all parameter sets: True

Quiet scripts

Pitfalls

• Scopes still matter. Hiding the message does not change the permissions; request the right scopes with -Scopes (Connect-MgGraph -Scopes).
• Confirm the session. Without the message, Get-MgContext (Get-MgContext) is the way to see who is connected. Cmdlets called before a connection fail with Authentication needed. Please call Connect-MgGraph.
• Alias. Connect-Graph, listed in the check above, is an alias of Connect-MgGraph and takes the same switch.
