I can confirm for other tenants that sometimes a negative value is returned for Quota.Used when queried via Graph API:
$Uri = 'https://graph.microsoft.com/v1.0/users/{0}/drive?$select=quota' -f $UserPrincipalName
$Response = Invoke-MgGraphRequest -Uri $Uri
I have not yet verified if the other values are correct.

Expected or Desired Behavior
Exporting accurate Quota values for OneDrive for Business sites that can be used for capacity planning analysis. For this purpose, I have to use Microsoft Graph.
Observed Behavior
I have used following methods:
The values returned for Quota.Used do not match the values from Admin Portal, under User Details Panel > OneDrive. The differences are not small, they can get to up to 600GB. Even more, in some cases Quota.Remaining > Quota.Total and this leads to Quota.Used to have a negative value.
I have double checked this using Powershell Module Microsoft.Online.SharePoint.PowerShell. Cmdlet Get-SPOSite -IncludePersonalSite:$true -Limit All -Filter "Url -like 'https://****-my.sharepoint.com/personal/*'" | select Url , StorageUsageCurrent, StorageQuota returns StorageUsageCurrent with the same value as the one displayed in Admin Portal under User Details Panel > OneDrive
Steps to Reproduce
I have not been able to reproduce the issue on another tenant until now, as I do not know the cause.
Thank you.
