Manage device access settings in Basic Mobility and Security

If you're using Basic Mobility and Security, there might be devices that you can't manage with Basic Mobility and Security. If so, you should block Exchange ActiveSync app access to Microsoft 365 email for mobile devices that aren't supported by Basic Mobility and Security. This helps secure your organization information across more devices.

Use these steps:

  1. Sign in to Microsoft 365 with your global admin account.

  2. In your browser, type: https://compliance.microsoft.com/basicmobilityandsecurity.

  3. Go to Organization Setting tab.

  4. Select Access restriction for unsupported MDM device and make sure Allow access (device enrollment is required) is selected.

To learn what devices Basic Mobility and Security supports, see Capabilities of Basic Mobility and Security.

First, save the script to your computer.

  1. Copy and paste the following text into Notepad.

        param (
     	[Parameter(Mandatory = $false)]
     	[PSObject[]]$users = @(),
     	[Parameter(Mandatory = $false)]
     	[Switch]$export,
     	[Parameter(Mandatory = $false)]
     	[String]$exportFileName = "UserDeviceOwnership_" + (Get-Date -Format "yyMMdd_HHMMss") + ".csv",
     	[Parameter(Mandatory = $false)]
     	[String]$exportPath = [Environment]::GetFolderPath("Desktop")
     )
    
     #Clearing the screen
     Clear-Host
    
     #Preparing the output object
     $deviceOwnership = @()
    
    
     if ($users.Count -eq 0) {
     	Write-Output "No user has been provided, gathering data for all devices in the tenant"
     	#Getting all Devices and their registered owners
     	$devices = Get-MgDevice -All -Property * -ExpandProperty registeredOwners
    
     	#For each device which has a registered owner, extract the device data and the registered owner data
     	foreach ($device in $devices) {
     		$DeviceOwners = $device | Select-Object -ExpandProperty 'RegisteredOwners'
     		#Checking if the DeviceOwners Object is empty
     		if ($DeviceOwners -ne $null) {
     			foreach ($DeviceOwner in $DeviceOwners) {
     				$OwnerDictionary = $DeviceOwner.AdditionalProperties
     				$OwnerDisplayName = $OwnerDictionary.Item('displayName')
     				$OwnerUPN = $OwnerDictionary.Item('userPrincipalName')
     				$OwnerID = $deviceOwner.Id
     				$deviceOwnership += [PSCustomObject]@{
     					DeviceDisplayName             = $device.DisplayName
     					DeviceId                      = $device.DeviceId
     					DeviceOSType                  = $device.OperatingSystem
     					DeviceOSVersion               = $device.OperatingSystemVersion
     					DeviceTrustLevel              = $device.TrustType
     					DeviceIsCompliant             = $device.IsCompliant
     					DeviceIsManaged               = $device.IsManaged
     					DeviceObjectId                = $device.Id
     					DeviceOwnerID                 = $OwnerID
     					DeviceOwnerDisplayName        = $OwnerDisplayName
     					DeviceOwnerUPN                = $OwnerUPN
     					ApproximateLastLogonTimestamp = $device.ApproximateLastSignInDateTime
     				}
     			}
     		}
    
     	}
     }
    
     else {
     	#Checking that userid is present in the users object
     	Write-Output "List of users has been provided, gathering data for all devices owned by the provided users"
     	foreach ($user in $users) {
     		$devices = Get-MgUserOwnedDevice -UserId $user.Id -Property *
     		foreach ($device in $devices) {
     			$DeviceHashTable = $device.AdditionalProperties
     			$deviceOwnership += [PSCustomObject]@{
     				DeviceId                      = $DeviceHashTable.Item('deviceId')
     				DeviceOSType                  = $DeviceHashTable.Item('operatingSystem')
     				DeviceOSVersion               = $DeviceHashTable.Item('operatingSystemVersion') 
     				DeviceTrustLevel              = $DeviceHashTable.Item('trustType')
     				DeviceDisplayName             = $DeviceHashTable.Item('displayName')
     				DeviceIsCompliant             = $DeviceHashTable.Item('isCompliant')
     				DeviceIsManaged               = $DeviceHashTable.Item('isManaged')
     				DeviceObjectId                = $device.Id
     				DeviceOwnerUPN                = $user.UserPrincipalName
     				DeviceOwnerID                 = $user.Id
     				DeviceOwnerDisplayName        = $user.DisplayName
     				ApproximateLastLogonTimestamp = $DeviceHashTable.Item('approximateLastSignInDateTime')
     			}
     		}
     	}
    
     }
    
     $deviceOwnership
    
     if ($export) {
     	$exportFile = Join-Path -Path $exportPath -ChildPath $exportFileName
     	$deviceOwnership | Export-Csv -Path $exportFile -NoTypeInformation
     	Write-Output "Data has been exported to $exportFile"
     }
    
  2. Save it as a Windows PowerShell script file by using the file extension .ps1; for example, Get-MgGraphDeviceOwnership.ps1.

    Note

    The script is also available for download on Github.

Run the script to get device information for a single user account

  1. Open Powershell.

  2. Go to the folder where you saved the script. For example, if you saved it to C:\PS-Scripts, run the following command.

    cd C:\PS-Scripts
    
  3. Run the following command to identify the user you want to get device details for. This example gets details for user@contoso.com.

    $user = Get-MgUser -UserId "user@contoso.com"
    
  4. Run the following command to initiate the script.

    .\Get-GraphUserDeviceComplianceStatus.ps1 -users $user -Export
    

The information is exported to your Windows Desktop as a CSV file. You can use additional parameters to specify the file name and path of the CSV.

Run the script to get device information for a group of users

  1. Open Powershell.

  2. Go to the folder where you saved the script. For example, if you saved it to C:\PS-Scripts, run the following command.

    cd C:\PS-Scripts
    
  3. Run the following command to identify the group you want to get device details for. This example gets details for users in the FinanceStaff group.

    $groupId = Get-MgGroup -Filter "displayName eq 'FinanceStaff'" | Select-Object -ExpandProperty Id
    $Users = Get-MgGroupMember -GroupId $groupId | Select-Object -ExpandProperty Id | % { Get-MgUser -UserId $_ }
    
  4. Run the following command to initiate the script.

    .\Get-GraphUserDeviceComplianceStatus.ps1 -User $Users -Export
    

The information is exported to your Windows Desktop as a CSV file. You can use additional parameters to specify the file name and path of the CSV.
