iOS - App Config - Outlook

We have the following set in App Config in Outlook.

<dict>
<key>com.microsoft.outlook.Mail.FocusedInbox</key>
<false/>
<key>com.microsoft.outlook.Mail.OrganizeByThreadEnabled</key>
<false/>
<key>com.microsoft.outlook.Contacts.LocalSyncEnabled</key>
<true/>
</dict>

We have confirmed the below works

 <key>com.microsoft.outlook.Mail.FocusedInbox</key>

<false/>

but the below settings don't work

    <key>com.microsoft.outlook.Mail.OrganizeByThreadEnabled</key>

    <false/>

    <key>com.microsoft.outlook.Contacts.LocalSyncEnabled</key>

    <true/>
