Rule action "Set Expiration Date"

If this option is enabled, any matching chat log documents will have their expiration date set to the number of days specified in the rule.

You can set a default expiration in the server configuration document to specify when all chat log documents should generally expire, and use action rules to override the expiration date for specific chat log documents.

Use case

You could set the default number to 90 days to mark all chat log documents as expired, and create an action rule to match chat log documents for all executives (CEO, CTO, CFO, etc.) in your company and expire those documents only after 365 days.

This option sets the ExpireDate field in each document to a date n days in the future. The ExpireDate value is used by the core IBM Domino archiving code to determine which documents should be archived/pruned/deleted.
