, Cloud App Security Failed to Scan any Files in Microsoft 365 Services (Applicable to Access Grant Using a Delegate Account)
Microsoft provides an option for administrators to choose whether to disable basic
authentication requests and allow only modern authentication to access SharePoint
Online/OneDrive, in the purpose of helping protect the services from brute force or
password
spray attacks. Cloud App Security uses basic authentication when
accessing SharePoint Online/OneDrive services by using a Delegate Account, that is,
combination of a username and a password. If the administrator enables basic authentication
when granting access but disables it after that, Cloud App Security
will not be able to pass the access control on the SharePoint Online/OneDrive side
and
scanning will fail.
To ensure proper scanning by Cloud App Security, make sure to
always enable basic authentication for SharePoint Online/OneDrive as follows:
On the Microsoft 365 admin center page, go to
, and click Allow under Control access from
apps that don't use modern authentication.This issue does not affect Microsoft Teams.
