+- **Microsoft 365 scan failed with "404 Not Found" for Google-only accounts** — accounts that exist only in Google Workspace were sent to the Microsoft 365 scan (`…/users/google:<email>/mailFolders`), which Graph cannot resolve. This happened when no Microsoft 365 account was ticked (the scanner then took every ticked account, Google-only ones included), and in scheduled scans whose profile contains Google-only accounts. The Microsoft 365 scan now skips Google-only accounts and reports how many it skipped; the Google Workspace scan still covers them.
+- **An M365 scan with no M365 accounts selected could scan the whole tenant** — with Google sources ticked and no Microsoft 365 account ticked, the Microsoft 365 part started with an empty account list, which the server treats as "every user". It is now skipped, with a note in the log.
