Notes

Restore an Item

The Exchange Mailbox task will place a message in the Storage Restore queue, requesting an item to be restored from an archive. When the Storage service has located the item, it places it in the Storage Spool queue and notifies the Exchange Mailbox task on queue R1.

Store Item

The Exchange Mailbox task will place a compressed email message on the Storage Archive queue, to be stored in an archive. If the compressed message is larger than 4 MB, it will be divided into 4 MB chunks (each labeled with a part number, such as "Part 1 of 5"). The message is reconstructed by the Storage service before storing.

The Exchange Mailbox task will place all emails to be stored onto the appropriate Storage service archive queue. Multiple Storage services may be configured, so the Exchange Mailbox task must select the correct Storage service for the vault store in which the archive resides.
