Enable Auditing – SharePoint Online Site Collection

Auditing is normally a required feature for most organization which wants to track user actions on a SharePoint site.  The functionality can be enabled at site collection level.  But most organizations try to enable it when they already have large number of of site collections.  Doing it manually by going to Site settings – Site collection audit settings would be a tough job if you have large number of site collections.  I wrote the script which may help someone.

The script uses both Client Side Object Model and SharePoint Online Management Shell cmdlets.  Make sure you change the location of SharePoint Client OM dlls.  I have set it as C:\CSOM.  You do not need to specify the Admin Url as I am creating it from User name.
