Adaxes fails to display Exchange Properties

Question

I am using an account with global admin permissions to o365, so it does not appear to be that as the issue. Adaxes V.2017.2 Trace logs showing the following

[11/02/2022 11:24:58] Connecting to Exchange Online as MeEmail@Mydomain.com. MaxRunspacesCount: 3 [11/02/2022 11:24:59] Connecting to remote server failed with the following error message : Bad Request For more information, see the about_Remote_Troubleshooting Help topic. [11/02/2022 11:24:58] Get-UMDialPlan [11/02/2022 11:24:59] Error: System.Management.Automation.Remoting.PSRemotingTransportException: Connecting to remote server failed with the following error message : Bad Request For more information, see the about_Remote_Troubleshooting Help topic. at System.Management.Automation.Runspaces.AsyncResult.EndInvoke() at System.Management.Automation.Runspaces.Internal.RunspacePoolInternal.EndOpen(IAsyncResult asyncResult) at System.Management.Automation.Runspaces.RunspacePool.Open() at #2e.#Vh.#h8() at #eb.#Wb.#j8() at #2e.#Uh.Execute(#ib command)

Any ideas?

Hello,

It looks like the issue is related to the deprecated Basic authentication in Exchange Online. For details, have a look at the following Microsoft article: https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online. To connect to Exchange Online using modern authentication, you need to upgrade to the latest Adaxes version and register your Microsoft 365 tenant using an application account. For information on how to register Adaxes as an app in Microsoft Azure, have a look at the following help article: https://www.adaxes.com/help/RegisterAdaxesAsAppMicrosoftAzure.
