Hi;

I am using Exchange 2013 Standard, and I created an agent mailbox for email checking before sending to 3rd parties company, I created a rule on the agent mailbox to move the email in "In Box" folder to the "Deleted Items" folder.  However; the email will sit on the "Deleted Items" system folder without purging, so I go to the Retention Policy and Retention Tag to create a tag for purge the deleted items and apply the policy to the mailbox.  After two days monitor, I still found the email still sitting on the "Deleted Items" folder.

I am wondering, if the retention tag and policy work for the standard edition?  I have set the retention period for 1 day

Hi,

When items are deleted, they are retained for 14 days. You'd want to change this to 0 days for this mailbox.

Command is below.

Set-Mailbox -Identity - "April Stewart" -RetainDeletedItemsFor 0

Let me know if this answers your question.
Thanks.

thanks, I will try.  after apply this shell script, is there anyway to push or force it active immediately?

Once you've run the command above, it'll be active and delete the deleted items each night. If you want to force it to run immediately then try running

Get-Mailbox -Identity "April Stewart" | Start-ManagedFolderAssistant
