Age based Enterprise Vault Domino archiving determines the age of items by the sorting of the EV Date column in the mailboxes view for example EV26C5E2CCF2B9267C.EligibleItemsByAge_XX.
The EV Date calculation formula is typically something similar to: (where the RestoredDate, if present, has priority before the DeliveredDate):
@If(@IsAvailable(EV26C5E2CCF2B9267C.RestoredDate) & !@IsNull(EV26C5E2CCF2B9267C.RestoredDate);EV26C5E2CCF2B9267C.RestoredDate;Form="Appointment" & @IsAvailable(EndDateTime) & !@IsNull(EndDateTime);EndDateTime[@Elements(EndDateTime)];Form="Task" & @IsAvailable(DueDateTime) & !@IsNull(DueDateTime);DueDateTime[@Elements(DueDateTime)];@IsAvailable(DeliveredDate) & !@IsNull(DeliveredDate);DeliveredDate;@IsAvailable(PostedDate) & !@IsNull(PostedDate);PostedDate;@Created)
The RestoredDate, if present, has priority before the DeliveredDate, PostedDate.
Once an item is restored it will follow the default process for the second archive. The new re-archive age is calculated against the corresponding setting in the Domino Mailbox Policy.
The registry key IgnoreEVDates was designed to bypass this rule. After review, this registry value does not work with Enterprise Vault for Domino.
