The Notes Add-In provides the facility to archive and recall messages while offline. This capability is useful if you need to access archived mail messages but are not able to connect to the Domino.
Offline Archive and Recall
The Notes Add-In's Offline Archive feature allows you to retain a full copy of archived messages on the Notes computer for recall access where a network connection is not available.
These copies will reside in the original mailbox until an offline archive operation has been performed. At that point, these copies will be moved to a local cache, leaving a stub in the original mailbox.
