Office 365 Exchange automatically delete deleted items

Question

How would I automatically delete email older than one week in deleted items folder? I have access to the mailbox through OWA. Would this be done using a Rule, Retention Policy or Archiving? Setting up a Rule or Retention Policy appears to only work on the inbox. No archiving option when I right click on the Deleted Items folder.

All mailboxes are managed through exchange in Office 365 Admin Center.

You can use retention policy to achieve your needs. RPT(Retention policy tag) is created for default folders, you can create a tag applied to delete items folder, and then link to a retention policy. Details see: Default folders that support Retention Policy Tags

Thanks Niko. I created a Retention Tag and assigned it ti a Retention Policy. The following message appears when I assign this Retention Policy to a user: Warning: Please update UseDatabaseQuotaDefaults to false in order to mailbox quotas to apply. Any thoughts? – C1TonyB Jun 29 '18 at 13:28
I set UseDatabaseQuotaDefaults to false using powershell. – C1TonyB Jul 02 '18 at 20:44
