When users access server based mail files, large Inbox document counts impose undesirable resource demands on the server. Smaller document counts will significantly reduce those demands.
When the Inbox maintenance feature is enabled, the Administration Process periodically runs the Inbox Maintenance agent on the users' home mail server. The Inbox Maintenance agent resides in the mail template, MAIL8.NTF. The agent removes documents from the Inbox based on settings defined in the Server document (and optionally mail policy settings documents). The settings that are specified in the Server document override the Inbox Maintenance settings in mail policy setting documents. The mail template MAIL8.NTF must be used as well as a Domino Directory created with or upgraded to the Domino 8 version of NAMES.NTF.
Messages removed from the Inbox continue to exist in other folders and views.
This feature is off by default.
Enable Inbox maintenance in the Server document by specifying a value in the field 'Start executing Inbox Maintenance agent on,' in the Server Tasks - Administration Process tab. In that field, specify one or more days of the week on which to run the Inbox Maintenance agent. In the field 'Start executing Inbox Maintenance at,' specify the time to begin running the agent. If a day is not specified in the field 'Start executing Inbox Maintenance agent on,' the feature is not enabled and the agent does not run regardless of whether the 'Start executing Inbox Maintenance at' field contains a time at which to run the agent. If Inbox maintenance is enabled but the field 'Start executing Inbox Maintenance at' is blank, the Inbox Maintenance agent runs at the default time of 1:00 AM.
In order to run Inbox Maintenance for all users on a home server, select the 'Maintain inboxes for only these selected users on this home server' option in the Server document, then enter an asterisk (*) in the 'Selected users' field. This indicates that all users whose home server (as defined in their Person document) is represented by the Server document will be affected.
