Can practices view when a user has accessed a document shared via Collaborate?

Once your Collaborate site has been created, you can enable the SharePoint audit feature to track user activity and understand which users have accessed the content, as well as the SharePoint Viewers functionality.

The following steps will need to be completed for each SharePoint site. For example, the default Client Collaborate site, and where selected for individual clients, the dedicated Client Secured Collaborate sites. 

Enable Audit Reporting

Note: The following steps must be completed when logged into the Collaborate site as the OneDrive Admin User.

1. In FYI, navigate to the Collaborate settings, either the Collaborate app for Client Collaborate sites, or Sharing Settings for dedicated Client Secured sites.
    
2. Click on the Collaborate Site URL.
    
3. The Collaborate site will open. Click on the Settings cog icon in the top right-hand corner.
   Note: It may take a few seconds for the icon to be displayed.
   
4. Click Site Information, and then the link View all site settings.
    
5. Click Site Collection Features.
    
6. Locate the Reporting option, and select Activate.
