I am trying to find if someone has successfully done this, basically automatize the deployment of an Add-in to Office 365

  • Client Secret: "1111111111111111111" (This is a secret that should be protected and not shown, I am having a look how to improve this)
  • APP ID: "2222222222222222222222222"
  • TenantID : "333333333333333333333333"

Followed:

https://learn.microsoft.com/en-us/powershell/exchange/app-only-auth-powershell-v2?view=exchange-ps

Created a Microsoft Entra App and added:

  • Office 365 Exchange Online and Exchange.ManageAsAPP API Permissions
  • In Microsoft Entra roles and administrators, Exchange Administrator added MSOfficeAddon Princial App

I tried the below, but not working

Import-Module -Name O365CentralizedAddInDeployment
Install-Module -Name O365CentralizedAddInDeployment

$clientSecret = "1111111111111111111" 
$appId = "2222222222222222222222222"
$tenantId = "333333333333333333333333"

$secureStringPwd = $clientSecret | ConvertTo-SecureString -AsPlainText -Force
$psCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList
$appId, $secureStringPwd
Connect-OrganizationAddInService -Credential $psCredential

Then two different outcomes errors

  • Connect-OrganizationAddInService : The Organization Add-In Service session was not initialized. Please call the Connect-OrganizationAddInService commandlet first.
  • OrganizationAddInService : The user name or password is incorrect. Verify your user name, and then type your password again.

I tested the PSCredentials and worked

Connect-AzAccount -ServicePrincipal -Credential $psCredential -Tenant $tenantId

    Afaik the corresponding endpoint only supports delegate permissions, you cannot connect via a service principal.
