Microsoft Entra Connect Sync Deprecation: What Hybrid Organizations Need to Know

Written by Pierre Bernolet | Jun 2, 2026 12:22:34 PM

Microsoft has officially started communicating the future transition from Microsoft Entra Connect Sync toward the cloud-native Microsoft Entra Cloud Sync model.

While the phased rollout will only begin from July 2026, the announcement is already highly relevant for organizations running hybrid Microsoft environments today. Especially because not every current setup is fully compatible with Cloud Sync yet.

For many IT teams, this is not an urgent migration project today, but this is an important signal about where Microsoft’s identity, endpoint and infrastructure strategy is heading in the coming years.

Executive summary

  • Microsoft is gradually transitioning from Entra Connect Sync to Entra Cloud Sync
  • The phased rollout starts from July 2026
  • Organizations with simple hybrid environments will migrate first
  • Advanced hybrid setups may still require Entra Connect Sync for the foreseeable future
  • Cloud Sync currently has limitations around Hybrid Microsoft Entra ID Join and certain device synchronization scenarios
  • Microsoft’s broader direction is clearly moving toward cloud-managed identity and reduced dependency on on-premises Active Directory
  • There is no immediate urgency, but organizations should start evaluating their hybrid identity strategy.

What is Microsoft changing?

Microsoft wants to gradually move organizations away from the traditional Entra Connect Sync architecture toward Entra Cloud Sync, a lighter and more cloud-managed synchronization model between:

  • Active Directory
  • Microsoft Entra ID
  • Microsoft 365 services

According to Microsoft, the goal is to:

  • reduce on-premises infrastructure complexity
  • simplify hybrid identity management
  • improve resiliency and reliability
  • strengthen security and Zero Trust readiness
  • reduce operational overhead

The migration will happen in phases.

Initially, Microsoft will only target organizations whose environments are already fully supported by Entra Cloud Sync. More advanced or complex hybrid environments will transition later, once additional capabilities become available.

Why this matters for hybrid environments

The biggest nuance in this announcement is that Entra Cloud Sync does not yet support every scenario currently handled by Entra Connect Sync. And that is particularly important for organizations with hybrid device management strategies.

Today, many organizations still rely heavily on:

  • On-premises Active Directory
  • Group Policies
  • Hybrid Microsoft Entra ID Join
  • Legacy applications and services requiring Active Directory
  • Legacy authentication dependencies

Many organizations are not only dependent on domain-joined devices, but also on legacy applications, file shares, authentication mechanisms and business-critical workloads that still require traditional Active Directory integration.

However, Cloud Sync currently does not offer the same level of support for certain device synchronization scenarios and advanced hybrid configurations.

Microsoft’s own readiness overview already highlights several scenarios that still require Entra Connect Sync today, including:

  • Hybrid Entra ID Join devices
  • certain multi-forest environments
  • advanced filtering requirements
  • large directory synchronization scenarios

This means many organizations will not immediately be part of Microsoft’s initial migration waves.

What this announcement really signals

Beyond the technical synchronization changes, Microsoft’s announcement also reflects a broader long-term strategy.

Over the past years, Microsoft has consistently been moving organizations toward:

  • cloud-managed identity
  • cloud-native endpoint management
  • reduced dependency on traditional on-premises infrastructure

This evolution aligns with technologies and approaches such as:

  • Microsoft Entra Joined devices
  • Intune-only device management
  • cloud provisioning
  • passwordless authentication
  • Zero Trust security models

Microsoft explicitly positions this transition around:

  • reducing on-premises complexity
  • improving security
  • simplifying identity operations

For many organizations, this does not mean abandoning hybrid environments overnight, but it does reinforce the direction Microsoft is taking across the broader Microsoft 365 ecosystem.

Be prepared

No need for panic: Organizations currently using Entra Connect Sync are not suddenly at risk. Microsoft has already confirmed that organizations relying on unsupported scenarios will not be targeted in the initial migration phases.

That means there is still time to:

  • evaluate the current identity architecture
  • understand dependencies on Active Directory
  • review Hybrid Join requirements
  • identify synchronization features currently in use
  • determine whether hybrid device management remains necessary long-term

In practice, the impact will differ significantly depending on the environment:

  • Smaller and less complex environments may transition relatively easily
  • Organizations relying heavily on Hybrid Join, device synchronization, writeback features or Exchange hybrid setups may require larger architectural considerations

In some cases, migration toward Entra Cloud Sync may also require infrastructure or design changes, so proper preparation matters.

What organizations should evaluate now

Rather than rushing into migration projects, organizations should first focus on visibility and readiness.

Useful starting points include:

  • mapping which features your current Entra Connect Sync deployment actually uses (password hash sync, pass-through authentication, writeback, filtering)
  • identifying Hybrid Join or device synchronization requirements
  • determining what those devices still need from on-premises AD: Group Policy, access to on premise file shares and printers, or line-of-sight to a domain controller for legacy apps
  • reviewing Exchange hybrid and any other writeback dependencies

Most importantly, organizations should start defining their longer-term identity strategy:

  • Will the environment remain strongly hybrid?
  • Or is a more cloud-native approach becoming realistic over time?

Final thoughts

The transition from Entra Connect Sync to Entra Cloud Sync is not just a synchronization update.

It is part of a broader evolution toward:

  • cloud-managed identity
  • simplified infrastructure
  • modern endpoint management
  • reduced dependency on on-premises Active Directory
  • Zero Trust security architectures

Organizations that understand this shift early will be better positioned to make gradual, strategic decisions rather than reactive infrastructure changes later on.

For many environments, Entra Connect Sync will remain necessary for the foreseeable future, but Microsoft’s long-term direction is becoming increasingly clear.
