New-ServicePrincipal : A parameter cannot be found that matches parameter name 'ObjectId'

Question

I have a strage error when I execute the below cmdlet in exchange online management.

New-ServicePrincipal -AppId xxx -ObjectId xxx -DisplayName "xxx"

Error: New-ServicePrincipal : A parameter cannot be found that matches parameter name 'ObjectId'

I have logged in with Connect-ExchangeOnline cmdlet with a user with Organization Management role.

I have checked and user is a part if RoleManagement.

PS C:\Users\Administrator> Get-ManagementRole -Cmdlet New-ServicePrincipal
Name            RoleType
----            --------
Role Management RoleManagement

According to the documentation, ObjectId is a valid param. https://learn.microsoft.com/en-us/powershell/module/exchange/new-serviceprincipal?view=exchange-ps

Answer 1

Hi @Yasitha Pandithawatta ,

Thanks for reaching out.

To Register Service Principal in Exchange:

New-ServicePrincipal -AppId <APPLICATION_ID> -ServiceId <OBJECT_ID> [-Organization <ORGANIZATION_ID>]

Make sure to use ObjectId from enterprise applications rather than object id of application registration. For the same application you registered in Application Registration. A corresponding application has been created in Enterprise Application as well. You need to pass object id from there while registering service principal in Exchange.

Hope this will help.

Thanks,

Shweta

Hi @Yasitha Pandithawatta ,

I have logged in with Connect-ExchangeOnline cmdlet with a user with Organization Management role.

Normally, the organization management role would be enough to use the ObjectID parameter of New-ServicePrincipal cmdlet:

For your situation, could you try typing "New-ServicePrincipal -O" and then pressing Tab and see if the "-ObjectID" parameter can be automatically filled?

It's also suggested to try connecting to Exchange Online PowerShell with another user who has the Organization Management role and see if there would be any difference.
