Users see the system message when they use the Enterprise Vault Web Access application. For example, you can use the message to indicate periods when there is going to be an interruption to the service because of hardware changes.
The message is not visible to a user who is using a shortcut to retrieve an item, but only to a user who is searching by using the Enterprise Vault Web Access application. The message is available to all users in the Enterprise Vault site.
To change the system message from the Vault Administration Console
