How to impose MFA for external users who may access encrypted messages?
We use Microsoft Purview labels to encrypt emails. We've disabled the OTP and would like to replace it with MFA. Is there an option? According to Microsoft documentation, this is not possible, however there may have been a workaround.

I believe for this to work the users would have to be guest users in your tenant and have MFA configured.
That way they could be able to authenticate with MFA
Also if the external users have their own Entra ID tenant this should work by default if im not misstaken
I would recommend that you try and invite an external email (for example Gmail or hotmail) to your tenant as a guest, configure MFA on that guest account and then see if you can share an encrypted email and authenticate to open it via MFA
Let me know how it goes
