Hi @Murali Mohan ,
Thanks for reaching out to Microsoft!
As per documentation, the Get-MgReportOneDriveUsageAccountCount
cmdlet in Microsoft Graph PowerShell is used to get the trend in the number of active OneDrive for Business sites. Any site on which users viewed, modified, uploaded, downloaded, shared, or synced files is considered an active site.
To run this cmdlet, you need the Reports.Read.All
permission.
Hope this helps.
