Hi all, I searched the communities but couldn't find the answers I need in regards to Office 365 Message Encryption.
We have a customer that wants to send encrypted emails from Outlook.
When a non-Microsoft recipient (e.g. Gmail user) receives these emails they cannot open them. They get the following:
It's my understanding that external recipients should be able to view encrypted email as per this article.
Can someone please help?
The sending user has a Microsoft 365 Business Premium license, and Azure Information Protection is active under the 365 tenant.

@telecaster Hey guys, this is interesting so I'm going to enter the conversation as well :) The first two options are associated with OME (built-in Office Message Encryption) and the two others are the pretty old default policy templates from AIP, not being created as of april 2019 for new customers. When using OME the external (anonymous) recipients should indeed get a link to enter the OME portal, either with their social id or pass code depending on the OME-configuration. Perhaps this is old news for you, I just wanted to say something entering the conversation!

Hi, I received your test message and whilst I was unable to access it via the Gmail web interface, I was able to open it via Outlook using the AIP viewer. This is going to be the only way that the Gmail users will be able to do this.
As @bec064 pointed out, the options you are using for encryption are the built-in OME / and older default AIP templates. I would recommend taking a look at updating your labels and policies. Could be a good time to start looking to migrate to Sensitivity Labels from the Security and Compliance Center, as Microsoft are planning to "sunset" the older AIP method in 2021 as per https://techcommunity.microsoft.com/t5/azure-information-protection/announcing-timelines-for-sunsett...
But, for the meantime, if you want Gmail accounts to access the encrypted emails, then Outlook and the. AIP viewer is going to be the way.

@telecaster Hey! There's really no need to look for third-party solutions when you have them built-in with your subscriptions. Not only in Office Message Encryption but you mentioned AIP as well. If you don't want to update your AIP settings or migrate to the unified labeling experience you could at least configure OME (for the end-users to choose as an option or as mail flow rule) as it should solve the particular external encryption issue.
"All Microsoft 365 end-users that use Outlook clients to read mail receive native, first-class reading experiences for encrypted and rights-protected mail even if they're not in the same organization as the sender. Supported Outlook clients include Outlook desktop, Outlook Mac, Outlook mobile on iOS and Android, and Outlook on the web (formerly known as Outlook Web App)."
Recipients of encrypted messages who receive encrypted or rights-protected mail sent to their Outlook.com, Gmail, and Yahoo accounts receive a wrapper mail that directs them to the OME Portal where they can easily authenticate using a Microsoft account, Gmail, or Yahoo credentials.
End-users that read encrypted or rights-protected mail on clients other than Outlook also use the OME portal to view encrypted and rights-protected messages that they receive."

@bec064 Thanks for your help. I'm beginning to understand the process now.
