Revise your OneDrive (Sync) restrictions when shifting to a Modern Workplace!

OneDrive client is unable to sync your folders.

What is a modern workplace these days without having your personal- or group data synced to OneDrive and taking the full advantage Microsoft’s cloud storage has to offer!? One of the most asked feature is silently configuring your OneDrive client to automatically synchronize your (personal) data.

Silent configuration

Over time the silent configuration of OneDrive for Business has been improved. In the early days we were designated using semi-automatic methods using registry keys and scripts by Per Larsen, old school group policies, or by custom OMA-URI policies to do the magic. Nowadays OneDrive can easily be configured using Administrative Templates (31 settings) via Microsoft Intune. (almost the same as GPO but wrapped in a modern UI called Microsoft Intune 😉)

SETTING NAME 
Prevent users from redirecting their Windows known folders to their PC 
Silently move Windows known folders to OneDrive 
Silently sign in users to the OneDrive sync client with their Windows cred..

Modern Workplace

Last week I was preparing a modern workplace demo fully automated and managed by cloud. This puts Windows Autopilot on the menu including automatic enrollment & management, encryption, policies, software deployment and…silently configuration of OneDrive for Business client.

Challenge

But what if silent configuration isn’t working as expected? This might become challenging where traditional and modern workplace comes together, you can end up in a situation where they do not fit. This will be the case when you’re preventing managed computers to sync OneDrive which are joined to a specific (Active Directory) domain(s).

It’s a no-brainer to opt-in for automatically (silently) configure the OneDrive for Business client. But in this case the OneDrive for Business client configuration was far from silent if you asked me! We ran into a challenge where OneDrive for Business client won’t be configured silently. Even when we tried to configure OneDrive sync manually, we didn’t succeed and ran into the following error “Sorry, OneDrive can’t add your folder right now“. So I reached out and contacted support 😉

OneDrive is restricted from syncing to only specified AD domains only.

Root cause

After some research I came across a blog of Chen Tian Ge who used Fiddler to take down a similar scenario. So after installed Fiddler myself, it was clear to me what caused the problem. I had found the undisputed proof. The reason for the failure is the fact the customer had implemented OneDrive sync client restrictions by using (AD) domain GUID. The modern workplace of course, did not meet the domain GUIDs requirement because it belongs to an Azure AD domain instead of AD joined domain.

Reproducing the root cause using sync restrictions based on (AD) domain GUID’s.

Restrict OneDrive syncing to specific domains

This feature works fine for computers which are joined to an Active Directory (AD) domain, but causes challenges when shifting to a modern workplace joined to Azure Active Directory (Azure AD).

Restrict OneDrive from syncing to specific (AD) domains.

Conditional Access

The underlying reason for implementing these controls is to make sure companies remain control of where your corporate data is going through. Lastly, preventing from ending up at unmanaged or non-compliant devices. Allow syncing only on computers joined to specific domains works for AD joined devices but doesn’t fit for a (native) modern workplace which is Azure AD Joined.

Azure AD Conditional Access provides tailored controls to address your corporate needs.

Azure AD Conditional Access control capabilities in Azure AD offer simple ways for you to secure resources in the cloud. The OneDrive for Business client works with the Conditional Access control policies to ensure syncing is only done with managed and/or compliant devices. For example, you might require sync to be available only on domain-joined devices or devices that meet compliance as defined by Microsoft Intune.

Alongside Conditional Access, Microsoft Cloud App Security (MCAS) can be used to implement complementary data leak prevention (DLP) policies to make sure you stay in control no matter where your corporate data goes. 

Get out of the old, get in with the new

Shifting from a traditional to a modern workplace isn’t just a matter of migrating the current, but a real transformation. Controls which worked well for many years in a traditional environment are often outdated by modern solution(s) that often work better and meet the revised needs/standards according a modern workplace.

Happy & safe syncing!

Microsoft Teams: How to overcome challenges with Windows Information Protection & Conditional Access

Recently Microsoft announced Microsoft Teams, a new chat-based platform in Office 365. For all mobile platforms (Android, iOS and Windows 10 Mobile) Microsoft released an native app, including a desktop app for Windows 10 and Mac OS X. The Microsoft Teams apps can be downloaded here. After I installed the Microsoft Teams desktop app on Windows 10 I bumped into the following funny message ‘Yikes! Looks like someone pulled the plug on the internet’.

Windows Information Protection…notes from the field! #MSIgnite

Windows Information Protection (WIP), previously known as enterprise data protection (EDP), helps organizations to protect corporate data against potential data leakage.

information-protection-needsThe concept is fairly simple and is actually based on defining two lists:

  • A corporate boundary list, which represents both on-premise & cloud network locations where managed apps can access corporate data;
  • A list of managed (trusted) apps, which are allowed to open, modify & store corporate data within the corporate boundary list.

In this blog we will look at some practical examples which you have to consider for a successful implementation of Windows Information Protection including a top 4 of recommended practices.

Blog series: Protect your Company Data using Enterprise Data Protection (EDP)

Recently I had the chance during a technical Friday jam session to play around with Enterprise Data Protection (EDP) with some other geeks .

EDP

In short Enterprise data protection (EDP) helps to protect against potential data loss without interfering end-user experience. EDP also helps to protect enterprise apps & data against accidental data loss on enterprise-owned devices, including personal devices that end-users bring to work without requiring changes to your environment or other apps.

Although EDP is introduced with Windows 10 release, the underlying technologies are common known. EDP is primary relying on Encrypted File System (EFS) and AppLocker. In a serie blog posts I will provid some guidance how EDP works and how to configure protected apps, Configuration Manager and Microsoft Intune.

Note!

Enterprise data protection is currently being tested with a number of enterprise customers, and will become available to Windows Insiders soon.

Stay tuned!

Part 1 – Introduction: Windows 10 Enterprise Data Protection – Under the hood…

UPDATE: Enterprise Data Protection is available again from Windows 10 Version 1511 rs1 builds if you want to test Enterprise Data Protection!

UPDATE: Stay on Windows 10 Version 1511 th2 build 10576 if you want to test Enterprise Data Protection!

In this blog I’ll cover a brand new Windows 10 feature, Enterprise Data Protection (EDP). The Microsoft Intune product team recently announced EDP policies as part of the Intune October service update. With this update you’re able to create and deploy configuration policies for Windows 10 enterprise data protection (EDP) settings, such as the list of apps that should be protected by EDP, enterprise network locations, protection level, and encryption using the new Windows 10 Enterprise data protection template.
