Hi All,
I am looking to help implement M365 DLP for email that can interrogate the properties of files to look for a specific metadata tag/property that has been applied by a 3rd party system.
- Is there an M365 learn page that lists the supported file types by M365 DLP? The only one I could find was this one - Use mail flow rules to inspect message attachments in Exchange Online
- For the supported file types shown on the linked article, can I use the "Document Property" condition in an M365 DLP rule to identify an attribute and presence of a value? (Similar to identifying an MSIP tag)
- For file types that fall outside those listed on the linked article, is there a way to interrogate the properties of these files using a DLP policy?
Thanks
David
