If you can’t view Microsoft Outlook attachments and receive an “Access is denied” notice, it’s likely that you’ve established a non-Microsoft email account as your primary email address. Follow these procedures to convert your primary email address to your Microsoft email address:
- Log in to your Microsoft account on the Microsoft account page.
