Syntax

New-ServicePrincipal
   -AppId <String>

Description

Service principals exist in Microsoft Entra ID to define what apps can do, who can access the apps, and what resources the apps can access. In Exchange Online, service principals are references to the service principals in Microsoft Entra ID. To assign Exchange Online role-based access control (RBAC) roles to service principals in Microsoft Entra ID, you use the service principal references in Exchange Online. The *-ServicePrincipal cmdlets in Exchange Online PowerShell let you view, create, and remove these service principal references.

For more information, see Application and service principal objects in Microsoft Entra ID.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

New-ServicePrincipal -AppId 71487acd-ec93-476d-bd0e-6c8b31831053 -ObjectId 6233fba6-0198-4277-892f-9275bf728bcc

This example create a new service principal in Exchange Online with the specified AppId and ObjectId values.

Parameters

-AppId

The AppId parameter specifies the unique AppId GUID value for the service principal. For example, ca73fffa-cedb-4b84-860f-d7fb8aa8a6c1.

A valid value for this parameter is available in the following locations:

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Online, Security & Compliance, Exchange Online Protection

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
