Microsoft rushed out version 3.10.1 of the Exchange Online management PowerShell module to fix a problem with certificate-based authentication. It seems like a change in an internal Microsoft identity platform caused the tokens issued after a successful connection to Exchange Online to not authorize the execution of further cmdlets. To their credit, Microsoft fixed the issue, but is this the kind of thing that should be caught in testing?

The latest versions of the SharePoint Online PowerShell module support app-only authentication (certificate-based authentication) for the Connect-SPOService cmdlet. In other words, applications can now connect to SharePoint Online to run administrative cmdlets by presenting a registered Entra ID app and an X.509 certificate instead of the credentials for a human SharePoint administrator. It’s a good change, even if I still prefer using the Graph APIs for SharePoint automation.
