Exchange Server Sync

Hi all,

i tried to Setup the Exchange Server Synchronisation on AX7.

The AX7 Environment is deployed on LCS and Log-in with Admin Account of an Tenant A. The Tenant A has no Outlook integrated, so i Setup a new O365 Demo Tenant B.

  • On the Setup Page Common->Setup->Microsoft Outlook Setup Assistant i Setup the admin User of Tenant A (in the data of User of Tenant a the E-Mail Adress of Tenant B is Setup)
  • the Exchange Seb Services URL is set to https://outlook.office365.com/EWS/Exchange.asmx and as
  • Exchance Server Login is set the User of the Tenant B.

With this Setup an error "The request failed. The remote server returned an error: (401) Unauthorized." Shows up.

is there a Setup on the User of tenant B to authorize the request to the Exchange Server, where can i Setup those Parameters.

is there any documentation on the Exchange Server Setup on AX7?

Kind Regards

    Hi Joeymike,

    Concerning documentation which you ask about I didn't find any. Concerning the issue with exchange synchronization in D365FO it is the problem witch ACS service point (Aad.ACSServiceEndpoint in web.config) and service principal (Aad.ACSServicePrincipal in web.config). When method ewsLogon from Microsoft.Dynamics.AX.ExchangeIntegration.Connection is called it checks Aad.ACSServicePrincipal with trustedissuers returned by Office365. Trusted issuers in Office365 you can check by Get-AuthServer in PS. In my case in D365 was 00000001-0001-0000-c000-000000000000 but in Office365 00000001-0000-0000-c000-000000000000. When they are different D365 return error "The request failed. The remote server returned an error: (401) Unauthorized.". So I changed Aad.ACSServicePrincipal to this returned by Office365. Error in D365 has been changed to the "The request failed. The request was aborted: The request was cancelled". I've setup the trace listener on System.Net and Microsoft.Dynamics.AX.ExchangeIntegration and it seems that second phase of getting authorization token failed with message Unknown AppId (realm@tenant). In my opinion problem is that Microsoft is still using ACS (https://accounts.accesscontrol.windows.net/tokens/OAuth/2) as the authorization service OAuth2 instead of AAD (https://login.microsoftonline.com/{tenant}/oauth2/token). Those two services accepts completly different JWT tokens so you can't simply change Aad.ACSServiceEndpoint in web.config. The problem is in Microsoft.Dynamics.AX.Security.S2SAuthentication.dll and Microsoft.Dynamics.AX.Security.S2SClientAuthentication.dll libraries. I've made the ticket on Microsoft support and waiting for response.
