Question

Im trying to setup xoauth2 for our helpdesk aplication.

Im following below commands to configure exchange.

Install-Module -Name ExchangeOnlineManagement

Install-Module Microsoft.Graph

Install-Module -Name AzureAD

import-module AzureAD

Import-module ExchangeOnlineManagement

Connect-AzureAd -Tenant “TenantID”

Connect-ExchangeOnline -Organization “TenantID”

$MyApp = Get-AzureADServicePrincipal -SearchString “YourAppName”

New-ServicePrincipal -AppId $MyApp.AppId -ServiceId $MyApp.ObjectId -DisplayName "Service Principal for IMAP APP"

Add-MailboxPermission -Identity "******@gianmariaricci.onmicrosoft.com" -User $MyApp.ObjectId -AccessRights FullAccess

Do you have any ideas why New-ServicePrincipal cmdlet is not working?

Answer 1

Hello there,

Ensure you have the right perms for this account. When in doubt, verify you have the Exchange Admin/Org Mgmt role.

The minmum permisson needed is "Role Management"

$Perms = Get-ManagementRole -Cmdlet New-ServicePrincipal

$Perms | foreach {Get-ManagementRoleAssignment -Role $_.Name -Delegating $false | Format-Table -Auto Role,RoleAssigneeType,RoleAssigneeName}

Do you have sufficient permissions to run that cmdlet? Do you hold one of these Exchange roles: Exchange Admin oar Organization Managment?
