Optimize Microsoft 365 traffic for remote workers with the Windows VPN client
This article describes how to configure the recommendations in the article VPN split tunneling for Microsoft 365 for the Windows VPN client. This guidance enables VPN administrators to optimize Microsoft 365 usage while ensuring that all other traffic goes over the VPN connection and through existing security gateways or tooling.
The recommendations can be implemented for the built-in Windows VPN client using a Force Tunneling with Exclusions approach, defining IP-based exclusions even when using force tunneling. Certain traffic can be split to use the physical interface, while still forcing all other traffic via the VPN interface. Traffic addressed to defined destinations (like those listed in the Microsoft 365 optimized categories) follows a much more direct and efficient path, without the need to traverse or hairpin via the VPN tunnel and back out of the organization's network. For cloud-services like Microsoft 365, this makes a significant difference in performance and usability for remote users.
Note
The term force tunneling with exclusions is sometimes confusingly called split tunnels by other vendors and in some online documentation. For Windows VPN, the term split tunneling is defined differently, as described in the article VPN routing decisions.
Solution Overview
The solution is based upon the use of a VPN Configuration Service Provider Reference profile (VPNv2 CSP) and the embedded ProfileXML. 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.
Typically, these VPN profiles are distributed using a Mobile Device Management solution like Intune, as described in VPN profile options and Configure the VPN client by using Intune.
To enable the use of force tunneling in Windows 10 or Windows 11 VPN, the <RoutingPolicyType> setting is typically configured with a value of ForceTunnel in your existing Profile XML (or script) by way of the following entry, under the <NativeProfile></NativeProfile> section:
<RoutingPolicyType>ForceTunnel</RoutingPolicyType>
In order to define specific force tunnel exclusions, you then need to add the following lines to your existing Profile XML (or script) for each required exclusion, and place them outside of the <NativeProfile></NativeProfile> section as follows:
<Route>
<Address>[IP addresses or subnet]</Address>
<PrefixSize>[IP Prefix]</PrefixSize>
<ExclusionRoute>true</ExclusionRoute>
</Route>
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. You must define a unique and separate <Route></Route> section for each required exclusion.
An example of a correctly formatted Profile XML configuration for force tunnel with exclusions is the following:
<VPNProfile>
<NativeProfile>
<RoutingPolicyType>ForceTunnel</RoutingPolicyType>
</NativeProfile>
<Route>
<Address>203.0.113.0</Address>
<PrefixSize>24</PrefixSize>
<ExclusionRoute>true</ExclusionRoute>
</Route>
<Route>
<Address>198.51.100.0</Address>
<PrefixSize>22</PrefixSize>
<ExclusionRoute>true</ExclusionRoute>
</Route>
</VPNProfile>
Note
The IP addresses and prefix size values in this example are used purely as examples only and should not be used.
Solution Deployment
For Microsoft 365, it's therefore necessary to add exclusions for all IP addresses documented within the optimize categories described in Office 365 URLs and IP address ranges to ensure that they're excluded from VPN force tunneling.
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 correct IP address ranges are always used.
An example of a PowerShell script that can be used to update a force tunnel VPN connection with Microsoft 365 exclusions is provided below.

Other Considerations
You should also be able to adapt this approach to include necessary exclusions for other cloud-services that can be defined by known/static IP addresses; exclusions required for Cisco WebEx or Zoom are good examples.
