We all know that retention works on SharePoint, and since OneDrive For Business and Office 365 Groups file areas are all SharePoint underneath, retention works just fine there too. Only issue is.. where the hell do I find the retention folder that the policy creates? just to see that it is active in an easy way. The “site contents” container isn’t visible in O365 Groups and OD4B, how do I know it ‘works’ without creating e-Discovery searches?
I took a wild shot while trying to figure this out and just pasted /PreservationHoldLibrary/Forms/AllItems.aspx at the end of my OneDrive path and.. worked like a charm. example where it should be pasted in the URL, I removed parts for formatting reasons: my.sharepoint.com/personal/johan_ollars/PreservationHoldLibrary/Forms/AllItems.aspx
Granted, for this to function something must have triggered the creation of the PerservationHoldLibrary, that is done by deleting something permanently from the site that is protected by a Retention policy.
This also works exactly the same way on O365 Groups & can save your Groups OneDrive data, even if you permanently delete the site! For O365 groups this is of now the only way to save your data from accidental deletion of the group object itself
