Hi everyone,

Apparently there is a loophole to leak data according to our cybersecurity team on the MacOS Outlook client using the “Share to Teams” feature

 

I am trying to disable the function for “Share to Teams” via a configuration profile on JAMF with the following configurations

Application & Custom Settings > Upload

Preference Domain: com.microsoft.Outlook

PLIST:

<plist version="1.0">
<dict>
    <key>com.microsoft.Outlook</key>
    <dict>
        <key>DisableShareToTeams</key>
        <true/>
    </dict>
</dict>
</plist>

I am wondering if anyone have any insights about this

Thanks in advance!!

Its not Jamf that determines if something can be managed or not. The application developer must make the given configuration manageable with the MDM framework and assign a key and values to it. Microsoft for the most part limits MDM compliance to how you log in to the apps (limiting login domains and the such), and shifts most everything else to the admin console to manage.

    Where are you finding information about this being a manageable setting?

    I’ve looked at Microsoft’s reference for Outlook for Mac and don’t see it there.

    Most settings like this are managed in the Microsoft Admin Consoles, Have you opened a case with Microsoft asking for directions?

    thank you to you both!! I just assumed it was possible on JAMF, but no real concrete evidence that it was possible. I will look on the Microsoft side, thank you!!
