Office 365 Message Encryption

Office 365 tenants often want to journal email from Exchange Online mailboxes. Things become a little more complicated when protected email is involved, but Exchange can decrypt protected messages and create journal reports with attachments containing the original encrypted message and a decrypted copy. That should be enough for journaling systems to process the journal reports and import messages into their repositories.

The September update of the Office ProPlus monthly channel delivers support for Office 365 sensitivity labels without the need to install the Azure Information Protection client. This is a step forward to make it easier for Office 365 users to be able to protect their most confidential information with encryption. More work remains to be done to upgrade the Office Online apps (including OWA), Outlook Mobile, and SharePoint and OneDrive. Will all this happen before Ignite?

Some people worry that Exchange Online mailboxes could be compromised by ransomeware and people will be forced to pay BitCoin to decrypt their messages. It’s certainly a possibility, but out-of-the-box solutions exist if you’re unlucky enough to be infected. That is, if you’ve done the necessary up-front planning to prepare for the worst to happen.,

Office 365 Message Encryption (OME) now offers an advanced set of features to Office 365 E5 tenants. You can have messages with specific branding delivered to different domains. Advanced OME also includes message revocation. Branding is a feature that will appeal to a limited set of tenants, but it would be nice if revocation was available to a wider set of Office 365 tenants.
