We are using Tfs2015.Update2.1 [14.95.25229.0].
We have vNext build definitions with a retention policy of 21 days. The maximum retention policy is set to 90 days. Yet we have builds that are over 100+ days old that have not been deleted (they still show up in the list of completed builds). It appears that the retention policy is not being applied at all. What can I do to verify that the retention policy cleanup process is actually running?
