Purging Mailbox-Related Business Processes
A business process will not expire (be eligible for purge or archive) if it is associated with a workflow ID for a document stored in a mailbox.
The business process will maintain a default expiration date of the completion date plus 10 years until the document is deleted from the mailbox. There is no default process for removing documents from mailboxes. The Mailbox Delete service must be scheduled or regularly executed by the customer to remove older documents from mailboxes when they are no longer needed.
For example, an AS2 document residing in an AS2 outbound mailbox is successfully routed to an external AS2 trading partner. An MDN is received, and the business process completes without error. The expiration in the business process is set to purge in two days. However, because the document is still present in the outbound mailbox, the actual purge date set on the business process will be the completion date plus 10 years. Only after the document is removed from the outbound mailbox, via the Mailbox Delete service, is the expiration date on the AS2 Send business process updated to the actual expiration value.
