We use a document management system for all of our invoices (filebound.com). Each site we have sends invoice to a site mailbox (EX: Bookeeper at site1 would send a scanned invoice to site1@company.com).
There is an unattended pc that monitors these mailboxes for these attachments, and imports them in to the document management system.
The message remains in the mailbox.
On exchange, what can I do to automatically delete any message, in each maibox, dated after a year ago? They want to retain anything before the year mark for record purposes and to make sure they were all imported.
Thanks.
