Request to Add a File Type for Applying Block and Detection Policies to MIP-Encrypted Documents

Please describe your idea in detail. What is your problem, why do you feel this idea is the best solution, etc.

We would like to request the addition of a file type so that MIP-encrypted M365 documents can be recognized as a distinct file format, allowing them to be included in the block and detection policy targets.
Currently, MIP-encrypted M365 documents are classified as Unidentified file types. As a result, when this category is configured for blocking or logging, other unnecessary garbage data is also blocked or recorded, causing an excessive increase in log volume and operational inconvenience.

How do you currently solve the challenges you have by not having this feature?

Currently, since M365 MIP-encrypted documents do not have a specific file type, we are also selecting the Unidentified file type to block and log them together.

Sorry to bother you while you are busy, but I am following up as we have not yet received a response to our previous inquiry.

Hello @jwkim,

Happy New Year!

I am sorry for the delayed response, I’ve just returned from my holiday vacation.
We will review your request and get back with a response as soon as possible.

Thank you for the patience!

Regards,
Simona

I apologize for the inconvenience, but could you please share an update on the status of the request?

Thank you.

Hi @jwkim,

Thank you for the follow-up.

Our team is still looking into this request and for a better technical analysis we kindly ask you to provide some examples of MIP encrypted files. Could you please attach the samples here so our development team can use them in this way?

Looking forward to your reply.
