The retention policy is the length of time of an item or a folder from the arrival time until it has been moved to the Deleted Items folder. In other words, the email retention settings state a time period for items until expiry, when the email is deleted. Basically, the retention period begins from the creation date (i.e., the sent emails) or the received date (i.e., the received emails).
