Can I open Access database files in Outlook? #M365AMA

In this episode, the #M365AMA panel discusses the following community question:

“I have this customer that occasionally receives emails of an access database .accdb file. Outlook doesn’t seem to play nice with that file type, for reasons I totally understand. But my question is if there is a way to receive that file type by email in outlook web app? This client is using m365 defender for o365 and I didn’t see any policies within threat management that would help me any. Obviously, I know there are other ways to share this file outside of email, but not looking for that at this moment.”
