Hello Cuddly,
Thanks for posting in the Microsoft Community.
Firstly, please be informed that there is no "File" option in the New Outlook, as well as AutoArchive. If you need Archive mails you can use the Archive button in toolbar.
However, in order to move mails to certain folder, you would need to set rules. Kindly make use of steps below to set rules for your requirements:
- Kindly click on Settings located at the top right corner of the Outlook windows
- In the Mail group, Click on Rules
- Click on Add new rule to set your rules
Here is a link that guides you better on setting Rules: Set up rules in Outlook - Microsoft Support
Best wishes,
