Folder Redirection to OneDrive on Windows 10 with Intune

Aaron Parker's stealthpuppy - Wed, 12/27/2017 - 11:15

If you’re deploying Windows 10 with Modern Management (Azure AD joined, MDM managed), you’ll likely have wondered about data protection – if users aren’t intentionally saving documents to their OneDrive folder, those documents are likely not synchronised and therefore not protected against data loss.

Traditionally managed PCs will have folder redirection (and offline files) so that user’s documents are synchronised when corporate network connectivity is restored. Some organisations will even have implemented folder redirection into the OneDrive folder via Group Policy, as a better alternative.

Implementing folder redirection for Windows 10 via Intune currently isn’t possible, so we need a creative solution to this challenge. With PowerShell scripts available to deploy via Intune, we can create a custom approach for redirecting important folders into OneDrive.

How Folder Redirection Works

Here’s an old, but a good article that covers how the Folder Redirection Extension works. It was written for Windows XP / Windows Server 2003, but the concepts are still the same in 2017. The article includes the following overview of folder redirection:

Folder Redirection processing contains five steps:

  1. Determine which user folders to redirect based on changes to Group Policy settings at the time of logon.
  2. Determine the target location specified for redirection and confirm the user has access rights to that location.
  3. If the target folder does not exist, the folder is created and the appropriate access control list (ACL) rights are set.
  4. If the folder exists, access rights and folder ownership are checked.
  5. If desired, the files contained within specified folders are moved to the new location, which also deletes them from the source folder if the source folders are local.

In this case, because we’re looking to redirect folders with the source and destination in the user profile on a local disk, we can skip steps 2, 3, and 4. Step 1 is obviously our main requirement and step 5 – moving existing data into the new folder on the same disk, should be quick and reasonably safe on modern PCs with SSDs.

Given that we don’t have Group Policy available to us, we need to implement steps 1 and 5 in such a way that we can be sure the redirection and move of data will be successful.

Implementing folder redirection in PowerShell 

A script that implements folder redirection using SHSetKnownFolderPath is available from here: SetupFoldersForOneDrive.ps1. This defines a function called Set-KnownFolderPath that can be used to redirect a known folder of your choosing to a target path and it works quite well. In its current iteration though, all it does is redirect the folder. 

Because we also need to move the folder contents, I’ve forked the script and added some additional functionality:

This version of the script updates the Set-KnownFolderPath function to ensure all known folders for Documents, Pictures etc. are covered and adds:

  • Get-KownFolderPath – we need to know what the existing physical path is before redirecting the folder
  • Move-Files – a wrapper for Robocopy.exe. Rather than implement the same functionality of Robocopy in PowerShell, the script references it directly to move the contents of the folder to the new location. This ensures that we also get a full log of all files moved to the new path.
  • Redirect-Folder – this function wraps some testing around the redirect + move functionality
  • Reads the OneDrive for Business sync folder from the registry to avoid hard-coding the target path
  • Implements redirection for the Desktop, Documents and Pictures folders.

My script could do with some additional error checking and robustness; however, it provides the functionality required to redirect specific folders into the OneDrive folder and can be re-run as required to ensure that redirection is implemented for each folder.

Deploying with Microsoft Intune

Intune allows you to deploy PowerShell scripts that run either in the user’s context or in the Local System context. 

Intune PowerShell script settings – user context. Not what we want.

Implementing the redirection script in the user context though fails when adding the SHSetKnownFolderPath class to the script session. Additionally, deploying the script in this manner will only run the script once – if the OneDrive client is not configured correctly when the script runs, the folder redirection will then never work.

Instead of deploying the folder redirection script with Intune, we can instead deploy a script that downloads the folder redirection script to a local path and creates a scheduled task that runs at user login to run the script. That way, we can be sure that the redirection script will run after the user has logged into the OneDrive client and set up the local sync folder in their profile. Additionally, this approach will enable folder redirection to run for any user logging onto the PC.

The script below will download the redirection script to C:\ProgramData\Scripts, create the scheduled task and output a transcript into the same folder.

Note that this downloads the redirection script from my public gist repository. If you implement this in production, I would highly recommend a more secure source for the redirection script.

Right now this script is quite simple – it will need to be updated to remove or update an existing script in the event you need to remove the script from Intune and re-add it.

To deploy the script via Intune, save it locally as Set-RedirectOneDriveTask.ps1 and add as a new PowerShell script under Device Configuration. Ensure that the script runs as Local System by setting ‘Run this script using the logged on credentials’ to No. This is required for creating the scheduled task. 

Adding the Create OneDrive Redirect Task script to Intune

Assign the script to a user or device group and track deployment progress in the Overview blade. A successful deployment will result in a scheduled task on the target PCs. 

OneDrive Folder Redirection Task Properties

When the script is downloaded and the task is created successfully, you’ll see the script and a transcript in C:\ProgramData\Scripts.

The downloaded folder redirection script

When the folder redirection script runs Robocopy to move documents, it will log those moves to %LocalAppData%\RedirectLogs.

Data copy/move logs

When implemented in this way, the script will run at user login and successfully implement folder redirection into the OneDrive for Business sync folder. The user will see a PowerShell script window (even though it’s set to hidden) – this could be fixed by pointing the scheduled task to a VBscript wrapper.

Configuring OneDrive

OneDrive should be configured for single sign-on for the best user experience. Not necessarily a requirement; however, it will make it quicker for users to be up and running and therefore quicker for the script to redirect the target folders.

Given the approach outlined in this article, it’s unlikely that the user’s folders will be redirected on the first login. Adding a delay to the scheduled task may allow redirection to work on the first run; however, this would require several tasks to run in order and Intune won’t necessarily run all tasks in the required order.

Summary

In this article, I’ve outlined an approach to implementing folder redirection with PowerShell, via Intune, into the OneDrive for Business sync folder. This uses a script deployed from Intune to Windows 10 Azure AD joined machines to download the folder redirection script and create a scheduled task that runs at user login to perform the redirection and data move.

Redirecting the Desktop, Documents and Pictures should provide protection for the key user folders. While redirecting additional documents is possible, they can often contain data that would be less this ideal for synchronising to OneDrive.

Redirected Documents folder in the OneDrive sync folder

The scripts I’ve posted here are provided as-is and I highly recommend testing carefully before implementing in production.

Bonus 

The folder redirection script will work for any enterprise file and sync tool, not just OneDrive for Business. For example, if you wanted to redirect folders into Citrix ShareFile, just read the PersonalFolderRootLocation value from HKCU\Software\Citrix\ShareFile\Sync to find the sync folder.

Deploy Citrix Receiver to Windows 10 with Intune and PowerShell

Aaron Parker's stealthpuppy - Sat, 12/23/2017 - 01:47

If you’ve Windows 10 Modern Management you’ll know that some applications present a challenge for deployment via Intune (or any MDM solution), because Windows 10 MDM supports the deployment of Win32 applications via a single MSI only. Applications such as Citrix Receiver, that are a single EXE (that wraps multiple MSI files), can be particularly challenging. You can create a custom wrapper to deploy Receiver, but this requires a packaging tool and some specific knowledge on how to package applications.

Microsoft Intune now supports deploying PowerShell scripts to Windows 10 machines, which can provide a more flexible framework for deploying complex applications. For Citrix Reciever, we can use this approach to target Windows 10 PCs for downloading the latest version of Receiver directly from Citrix and install it with any required command line options. This ensures that devices always install the latest version and the Intune administrator only ever has to create a single deployment option via a PowerShell script.

Installing Citrix Receiver

Here’s a simple script to detect whether Receiver is installed and if not, download and install Receiver using a specific set of command line options.

The script could be extended with some additional error checking and logging to provide some additional auditing of the installation, but I have tested this successfully.

Deploying via Intune

Deploying the script via Intune is done just like any other PowerShell script. Save the script locally and then in the Azure Portal, Intune blade, under Device Configuration / PowerShell scripts, add a new script and upload the saved script.

Adding the Install-CitrixReceiver.ps1 script to Intune

Assign the script to an Azure AD group for target users or devices. Your script should then be listed as an assigned script. 

Install-CitrixReceiver.ps1 alongside other PowerShell scripts

Once deployed, we can track successful installations in the Overview blade. Note that the script will only run once per target device – it should be unlikely that the device will receive the script and have it fail (e.g. fail to download the CitrixReceiver.exe), but there could be edge cases where installation fails as a result of some very specific circumstances.

Citrix Receiver deployment overview

Post-deployment, we can rely on the updater functionality built into the latest Receiver releases to keep end-points up to date.

Summary

We used a simple approach to the deployment of a non-MSI application to Windows 10 via Intune with a PowerShell script. A simple example that enables deployment of Citrix Receiver with no special packaging and we can be sure that because the end-point downloads Reciever directly from Citrix, the latest version will be deployed each time.
