Hi @Jake Sokol ,
If the folders were created under on my computer folders, you can follow these steps to show them on the Outlook menu> click Preferences> Under Personal Settings > click General, under folder list clear the Hide On My Computer folders check box and select the Show all account folders check box
If your account type is O365 for business or Exchange, you can try to remove your account and then add it back to Outlook and then the data will be resynced.
