Hi @tammypatterson,
Welcome to Microsoft Q&A, and thank you very much for reaching out.
Based on your description, you can try searching for an email that was inside the folder to confirm it still exists. Then, expand all folders to check whether the folder was moved and nested under another one. If you still can’t find it, please also check the Deleted Items folder.
I also found an external article that provides an alternative approach. Feel free to review it to see if it helps further.
