In a perfect world, this should probably not happen. Token Refresh Jobs are scheduled to execute every 7 days and—if they always execute according to schedule—the refresh tokens will not expire. However, things tend to happen in the real world. If a server is down or some other issue occurs that prevents the token from refreshing, it will exceed the 15 days since it was created and expire.

For any expired token—regardless of cause—the remedy is the same. Look for any that show as Expired and execute the Reactivate function (see preceding sections).
