Hi Eben,
Welcome to our forum!
from your description, you are having trouble with Outlook mobile not showing notifications for emails that are automatically moved to a specific folder.
I have tested it on my mobile and the test result is the same as the problem you are experiencing. Email notification is available only to Inbox.
For this case, you can click on Settings - Help and Feedback - Feedback to Microsoft - Make a suggestion.
