When viewing a list in Blackbaud NetCommunity, the date it was last refreshed is earlier than the last time the List Acquisition and Refresh setting was scheduled.
The List Acquisition and Refresh setting in Blackbaud NetCommunity Configuration only defines the time at which Blackbaud NetCommunity will refresh any lists that have been manually queued for refreshing. A list is manually queued by editing the list and clicking the Refresh List button.
Lists are automatically refreshed each time an email message is sent to the list. It is not necessary to manually refresh a list before sending a message to it, as such.
