The Archiving function on our Cloud packages differs slightly from the On-Premises feature, due to our cloud infrastructure.
To configure Archiving on a Cloud package, please visit ACP -> Community -> Forums, Settings -> Archiving sub-tab.
By default, Archiving is enabled for posts which are more than 1 year old:
You may disable Archiving entirely, or you may select an Archiving cutoff date which is longer than one year, in one year increments.
Archived topics cannot be posted in or edited, and will not show in search results. You can unarchive topics after they've been archived if you change your mind.
