Hi Danny,
It sounds as though the previous employee set up content filtering. If this is the case you can go to Settings > Filtering > Content Filtering to see any filters that were set up. You can delete the filters from there so new messages will only be directed to your inbox. If you want to remove the messages from the other folders you can either select the message(s), click Actions > Move and select the new location, or you can click and drag the messages to the new location.
If you need any further assistance feel free to contact customer service at
sales@smartertools.com or 877-357-6278.
