A retention policy deletes documents after workload is removed from the policy
Note
This issue was resolved on June 19, 2020 and should no longer affect retention policies.
If a retention policy is set up for specific workloads such as SharePoint Online, OneDrive for Business, or Exchange Online, but the OneDrive for Business workload is removed from it at a later time, the actions that are generated to comply with the policy continue to run until they are finished.
For example, a retention policy is enabled to move all OneDrive for Business documents that are created before a specific date to the Recycle Bin. If this policy is later disabled for OneDrive for Business, it will not stop the documents from continuing to be moved to the Recycle Bin.
