Multiple Failed SignIn Events

Hello,

 

There are more than 100 failed sign in events from authorised device with interval 2m related to these three Application:

- Office Online Maker SSO

- Office Online Core SSO

- Office365 Shell WCSS-Client

 

For what these application related to?

 

Thank you,

 

  • They are all 1st party Microsoft applications.

     

    Office 365 Shell WCSS-Client is the browser code that runs whenever a user navigates to most Office365 applications in the browser.

     

    Office Core and Maker SSO are what they say on the tin, single sign-on applications.
