External users cannot open encrypted email
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 ChristianBergstrom 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-sunsetting-label-management-in-the/ba-p/1226179
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.
We had been using the previous version of OME; however, encryption via the mail flow rule that was set up stopped working for one user some time ago. Other accounts, and new ones, were not affected. Suddenly on December 16 the previous version of OME stopped working for all. We switched to the new version, Azure Information Protection. It works for internal staff members who are using the Outlook client. It does not work for external recipients, as described by telecaster below. We have read extensively on what to do, reviewed the steps provided below, and have run numerous PowerShell scripts that are published in Microsoft's extensive library. All our efforts have not brought us closer to collaborating securely with outside users, which we were able to do with the previous version of OME before December 16. And out internal users cannot decrypt their secure messages when signed in to Outlook Web Access e-mail. Does anyone have suggestions? Where do we go from here?
