Hello,
There is already a post for this question but it seems to be archived for new posts. Please refer to https://world.episerver.com/forum/developer-forum/-Episerver-75-CMS/Thread-Container/2017/8/content-expired-event/
Is there an event that runs when the content is expired or is expiring? I tested SavingContent but it does not get fired in this case. I am also not interested in scheduling/scheduled content since they run at the time when the page is marked with an expiration date, not at the time of the expiration date.
