Some time ago, Microsoft has delivered an Office 365 mobile admin app, Even if the app is being updated frequently, some time you may think that some settings/info are missing.
You can get more ; just go the Settings page of the app and tap at least 5 times the version number shown bottom left.
A more options section will then appears, allowing you to select additional More Settings section which then allow you to define additional settings like Partner (if you are partner), groups, alias…
This section will change over the time as some of these settings may come on later release or additional/new ones will be added.
Enjoy with this trick
