The solution is based upon the use of a VPN Configuration Service Provider Reference profile ([VPNv2 CSP](https://docs.microsoft.com/windows/client-management/mdm/vpnv2-csp)) and the embedded [ProfileXML](https://docs.microsoft.com/windows/client-management/mdm/vpnv2-profile-xsd). These are used to configure the VPN profile on the device. Various provisioning approaches can be used to create and deploy the VPN profile as discussed in the article [Step 6. Configure Windows 10 client Always On VPN connections](https://docs.microsoft.com/windows-server/remote/remote-access/vpn/always-on-vpn/deploy/vpn-deploy-client-vpn-connections#create-the-profilexml-configuration-files).
Typically, these VPN profiles are distributed using a Mobile Device Manager solution like Intune, as described in [VPN profile options](https://docs.microsoft.com/windows/security/identity-protection/vpn/vpn-profile-options#apply-profilexml-using-intune) and [Configure the VPN client by using Intune](https://docs.microsoft.com/windows-server/remote/remote-access/vpn/always-on-vpn/deploy/vpn-deploy-client-vpn-connections#configure-the-vpn-client-by-using-intune).

Entries defined by the **[IP Addresses or Subnet]** and **[IP Prefix]** references will consequently be added to the routing table as _more specific route entries_ that will use the Internet-connected interface as the default gateway, as opposed to using the VPN interface.

For Office 365, it is therefore necessary to add exclusions for all IP addresses documented within the optimize categories described in [Office 365 URLs and IP address ranges](https://docs.microsoft.com/office365/enterprise/urls-and-ip-address-ranges?redirectSourcePath=%252fen-us%252farticle%252fOffice-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2) to ensure that they are excluded from VPN force tunnelling.
This can be achieved manually by adding the IP addresses defined within the **optimize** category entries to an existing Profile XML (or script) file, or alternatively the following script can be used which dynamically adds the required entries to an existing PowerShell script, or XML file, based upon directly querying the REST-based web service to ensure the addresses ranges are always used.
