If you can see there should be X number of new emails but your Outlook folder is empty?
Most likely the items are not actually deleted but are being filtered from view in some way. To resolve this issue, you need to change the filtering options.
Filtering options vary, but some of the more common filtering options are as follows:
- Date received
- Read/Unread status
View options will vary slightly, depending on the version of Outlook that you are using. To change the view options in Outlook, follow these steps.
