Minimizing the potential performance effects of shortcut deletion

A new feature in Enterprise Vault 9.0 is the automatic deletion of shortcuts in Domino mail files. If you have shortcuts that were created by an earlier Enterprise Vault release we recommend that you implement shortcut deletion gradually.

If you implement shortcut deletion for all mailboxes immediately, the automatic deletion of old shortcuts from thousands of mailboxes can affect the Domino server and network performance. In particular, the shortcut deletion can affect compaction, replication, and index updates.

To minimize these effects, you can use either of the following methods to introduce shortcut deletion gradually:

Add shortcut deletion to groups of mailboxes.
Use an age restriction to limit the number of shortcuts that are deleted. For example, you could delete those shortcuts that are more than 36 months old, then later change the policy to delete those shortcuts that are older than 30 months old, and so on.

See the section "Configuring mailbox policies" in Setting up Domino Server Archiving for details of how to set up shortcut deletion.
