From email clients like outlook, usually deleting and re-adding the account in outlook will refresh the mail cache and fix this. However, from WebMail, logging out and back in should be enough to refresh the account cache. You can also try re-initializing Ability Mail Server to make sure any account caches are reset. If all else fails try deleting the user in Ability Mail Server (but not the files) and re-adding it. We recommend making a backup of all files before doing this just in case.
