How can I authenticate against Exchange Online using service principal?

Question

I need to connect to Exchange Online using specific service principal, but I am getting error

I am trying to authenticate via Connect-ExchangeOnline -AccessToken $token -Organization $organization

We have latest Adaxes version installed btw aka 3.8.0 version of the ExchangeOnlineManagement module is used automatically.

Hello,

Unfortunately, there is no such possibility. Using method $Context.CloudServices.ConnectExchangeOnline() is the only option in Adaxes scripts. However, thank you for the suggestion. We forwarded it to the corresponding department for consideration.

Hello,

Also, try the below command in both Windows PowerShell and PowerShell 7. Does it give the same results?

Get-Module ExchangeOnlineManagement -listavailable

There was 3.6.0 version. I have deleted it and restarted Adaxes services.

Now no ExchangeOnlineManagement is detected in desktop nor core powershell, but I am getting still the same error.

Hello,

It looks like Adaxes is unable to install the module automatically. You can do it manually using the below command.

Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.8.0 

After the installation, restart the Softerra Adaxes Service Windows service.

I have tried to explicitly import installed 3.8.0 version but no difference.

Anyway I can see that the Adaxes builtin EXO module is being imported

So I don't think this is the problem here.

(the output is retrieved via command get-module | foreach {Write-Warning "$($_.Name) $($_.Version) $($_.Path)"} and is made before the exo auth occurs)

Hello,

Do we understand correctly that you face the error after clicking Generate for the report with the script?

Are you able to view properties of Exchange Online recipients in Adaxes via the UI? For example, by just opening properties of a user in the Administration console and activating the Exchange tab.
