Microsoft Windows Phone 8.1 Apps

Legacy Mobile Device Management (MDM) service retiral: November 1, 2021.

From November 1st, any Android, Windows Mobile or legacy MDM iOS devices (these are iOS devices that are not enrolled in Apple Device Management(ADM) service) will no longer be supported. You are not required to take action on these devices as we will automatically retire the service.

Go to the Mobile Device Management page for further information.

This change does not affect iOS devices enrolled in ourApple Device Management(ADM) service) which will continue to be supported and offers numerous advanced management options not available in the legacy MDM service.

Unlike Apple iOS and Google Android, which use a single client for communication, Microsoft Windows Phone 8.1^ utilizes both a MDM client built into the Operating System and app which runs as a background task.

The built-in client is responsible for configuring the email, passcode policies, device restrictions, remote and providing some device information whilst the app provides those indicators not available from the client including the device location, battery level, RAM, timezone as well as some additional information.

Background Task

When opening the app the background task is automatically added - Step 2 of Microsoft Windows Phone 8.1 provisioning - this task runs approximately every thirty minutes and uploads data based on the hourly or daily check schedule.

Please be aware that the Operating System will attempt to schedule multiple background tasks to run together, so the MobileGuardian may not always run exactly on thirty minutes.

To check whether the background task was successfully added to the device, go to the apps tray, BatterySaver, MobileGuardian. If the options to enable or disablebackground data are displayed then the task was created. Where these options are not available just open the MobileGuardian app to generate.

Background Task Expiry

To prevent apps that are not regularly opened consuming data and battery their associated background tasks automatically expire after two weeks.

As this counter mechanism can affect the MobileGuardian app, where the expiration is within the next two days a notification is displayed locally to the user every time the background task runs and once the message is clicked the MobileGuardian app is opened and the counter reset.

If the task expires, for example the phone was switched off, the MobileGuardian app must be manually opened to re-configure the background task.

Power Saving Mode

To conserve power background tasks do not run when power saving mode is active on the phone, indicated by a heart on the battery icon.

As not all tasks should be stopped when in this mode there is the option to Allow this app to run in the background even when Battery Saver is on which can be accessed from the apps tray, BatterySaver, MobileGuardian.

Extend the Background Task

To avoid manually opening the app or clicking on the notification every two weeks the MobileGuardian app can be pinned to the start screen, this has the effect of updating the tile every time the background task runs and extending its life.

MobileGuardian is added to the start screen from the app trayhold down the MobileGuardian app then select pin to start.

^ Please be aware that Windows 10 is currently unsupported.
