My company has an on prem Exchange 2013 environment running CU15. I want to clean up the deleted items folder for all of my users; I am looking to delete items older than 90 days from this folder only. I have already implemented a retention policy with the 90 day retention tag for the deleted items folder. That policy is working and I can see the tags being applied. However I do not want to wait 90 days for the items to be purged, I want to delete items older than 90 days right away and then have the retention policy keep up day to day. I have spent hours researching this and can not find a way to complete this. Thank you.
