Microsoft Entra Connect lifecycle status — the real story
Microsoft Entra Connect (Entra Connect Sync, formerly Azure AD Connect) is the server installed on-premises that synchronises on-premises Active Directory identities to Microsoft Entra ID for hybrid identity. Every release is a full version number, and Microsoft publishes a retirement date for each 2.x version on the Connect version history page.
Since March 2023 every 2.x version retires 12 months after a newer version is released, so the newest version has no end date until its successor ships. Microsoft has also retired versions early to align with security changes, as it did for the 2.3 releases. All 1.x versions (Azure AD Connect V1) are unsupported and no longer synchronise at all.
With a retirement date roughly a year after each new release, an Entra Connect server that is installed once and left alone falls out of support quickly, even though it sits in the identity tier. Microsoft's guidance on the version history page is to always install the latest version for new installs and to upgrade to the latest version before the current one retires.
Microsoft Entra Connect release and support pattern
Across the 18 release lines with a published release date, Microsoft Entra Connect has shipped a new line roughly every 2 months (median interval). A line typically stays supported for about 1.2 years from its release to its end-of-life date (measured on the 17 lines with both dates published).
Of the 19 release lines tracked, 12 are past end of life and 7 are still within support; 1 is marked end of life without a published date. The newest line, 2.6.92.0, was released September 23, 2026. The next scheduled end of life is 2.5.79.0 on October 23, 2026 — 13 days from this build. The longest-supported line currently published is 2.6.91.0, to September 23, 2027.

What does Microsoft Entra Connect end of life mean for your organization?
When a version of Microsoft Entra Connect reaches end of life, the maintainers stop issuing security patches. Vulnerabilities discovered after this date are publicly disclosed on the National Vulnerability Database, exploit code appears on GitHub, and your systems remain permanently exposed.
The CVE blind spot: A CVE-based scan does not show the accumulation of unpatched vulnerabilities in EOL software. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. With a zero-day, nobody knows about the vulnerability. With EOL software, the vulnerability is public — listed, rated, and often weaponized — but no vendor patch is coming. This is one of the most dangerous gaps in enterprise security posture.
Organizations running EOL Microsoft Entra Connect should treat it as a vulnerability class in their risk register, apply compensating controls (network segmentation, enhanced monitoring, access restriction), and prioritize migration to a supported version.
Your options when Microsoft Entra Connect reaches end of life
There are four realistic paths. Which one is right depends far more on how long the system needs to keep running than on the version you are on today.
| Option | Best when | Watch out for |
|---|---|---|
| Move to a supported version | The system will outlive the current version's support window and you can schedule the work | Budget for compatibility testing, not just the upgrade itself — that is where the real cost sits |
| Replace the component | The project is unmaintained, or a better-supported alternative exists | The replacement has its own lifecycle and its own end-of-life date — you are changing vendors, not escaping the problem |
| Buy extended support | Migration is genuinely underway but cannot finish before the deadline, or the workload is frozen by certification or a third-party application | A bridge, not a destination — every year purchased is a year the migration still has to happen |
| Document accepted risk | The system is isolated, short-lived, or scheduled for retirement | Only defensible with real compensating controls and a written decision — auditors treat undocumented end-of-life software as a finding |
How to choose, in one question: how many more years does this system need to run? Under a year, extended support (where it exists) is usually cheaper than an emergency migration. One to three years, migrate — support purchased repeatedly costs more than doing the project once, and the project only gets harder as the version ages. Indefinitely, migrate now and plan the next migration before it surprises you.
Worth saying plainly, because vendors selling extended support rarely will: extended support is often the more expensive choice over a multi-year horizon. It is the right answer when a deadline is genuinely unreachable, not as a default. Compare the annual fee against the one-time cost of migrating before committing to either.

Extended Support Options
If you cannot migrate immediately, extended support vendors provide continued security patches for EOL Microsoft Entra Connect versions. This is a bridge, not a permanent solution — plan your migration in parallel.
Microsoft Entra Connect has 12 versions past end of life — security patches have stopped, but CVE disclosures haven't. Extended support past the official date exists for many products in this position — whether it exists for Microsoft Entra Connect is exactly what we check. Tell us where to reach you and we'll reply with matched options and pricing guidance — or an honest "no vendor covers this."
