Encryption of documents via Sensitivity label and external parties
Hi all, I am wondering whether I can get some better picture of what would be the impact of sharing encrypted documents to external parties. My scenario: I am using MS Purview to create sensiti...
- In my testing, Gmail doesn't support documents encrypted with sensitivity labels.
Encrypted emails are handled differently. The encrypted email is sent in a "wrapper" email. If the recipient's email client supports the encrypted format, the client decrypts the email.
If the client doesn't support the encrypted format (e.g. GMail), then the end user sees the wrapper message, which redirects the recipient to a Microsoft site where they can go through the one-time-password check and view the email plus attachments.
So, you may need to send attachments as encrypted emails to ensure that non-supported recipients can easily view attachments.

- ...that is exactly what I've found out as well. For encrypted attachment, I need to make sure email itself is encrypted as well to force the authentication through OTP and have it all opened in online "Microsoft 365 Message Encryption Viewer". Encrypted attachment can be then opened there.
