Exchange Online - Tag for external email messages received

I saw in the admin center that this is enabled, and you can make a PowerShell change to active and am glad to see this, but I notice that is says, "This feature is available in Outlook on the web, the new Outlook for Mac, and Outlook mobile (iOS and Android)." When will this feature be added to Outlook for Windows? Interesting that it is online, Mac, and mobile but not Microsoft's flagship OS, Windows.

    Can I assume if my Powershell recognizes the CMDlets Get-ExternalInOutlook and Set-ExternalInOutlook that the Feature is already enrolled in my tenant?

    I have tested this successfully in my DEV-tenant. There I have set the update release for all users to targeted release and it worked 1-2 hours later.

    Then I wanted to enable it in a customer tenant as well. Powershell CMDlets are recognized as well. Here I have set the targeted release for a small bunch of users before the weekend. Unfortunately there is no external tagging, yet.

        Does anyone know of any docs that give more technical details of how this works aside from how to enabled via powershell and the roadmap annoucnement? Ive been asked to provide info on how it functions and how it would protect against spoofed emails. In my own tests I couldnt get a spoofed email through so I guess 365 provides good protection anyway but im looking for actual details I can give rather than just saying "it works"

    Have you tried enabling this feature? Both commands "Get-ExternalInOutlook" and "Set-ExternalInOutlook" are not recognized on my end. We are using the Exchange Online Service and I even used the Exchange Online PowerShell V2 module.

      I got the commands to work for my test tenant but it doesn't show on Windows yet but did on the other devices in a test and so I want to hold off until it is available with Windows.

      I'll second this. Connecting with the Exchange Online PowerShell V2 module and running Get-ExternalInOutlook results in "The term 'Get-ExternalInOutlook' is not recognized [...]"

      The Message Center article (MC243047) says the command is available now but my guess is that it will take some time for this feature to roll out to all tenants, or is dependent on an unreleased version of the powershell module.

      Anyone from MS have any idea when this will actually be available?

        I just ran the powershell commands again today and they worked this time.

        If it's still not working for anyone else, you might just need to wait a bit more for it to be available in your tenant.

         

        As for the original purpose of this thread - hopefully someone will have some idea if/when Outlook for Windows will get the tag feature as well.
