ChristianJBergstrom thanks for your quick answer.

If I understand you well, OME don´t have a solution for this use case, right?

To somehow block all except Outlook Windows dont think it is a good idea.

It will be challeging to assure never get access..

Maybe there is a way via Powershell?

Question is if it is possible...

 

Thanks a lot anyway 🙂

    OME isn't really designed to handle complex access situations. If I were you. I'd consider using a sensitivity label that restricts access to a limited set of reciipients.

      Agreed, but if going down that road it needs some structure and planning incl. people from your business (to classify and protect). I.e. the very opposite from the easy to use built-in encryption with OME josecachairo

        hi all,

        meanwhile we tested and indeed delegates CAN´T read encrypted emails. So it is working as we expected and Microsoft information is confusing (not clear enough) to this matter.

        So if you use OME, delegate can´t not read those emails (encrypt only).

        I recommend you to test it also in iOS, Android to be sure.

    You’re correct. OME cannot accomplish what you’re looking for. There used to be a MIP UserVoice request for this scenario, but as Microsoft has closed down UV for this and other products I don’t know what has happened to it. Sorry..
