Does the decision not to support or provide updates for M365 Apps for enterprise on Windows 10 where customers have purchased Extended Security Updates not negate the whole purpose of purchasing ESU's. Whilst the ESU's would protect Windows 10, it introduces vulnerabilities into M365 Apps for enterprise due to it not being updated?

    Agreed! ajp999 ESU does not help it's customers using M365 Apps at all since it leaves them in a non-compliant position after Oct 14th even if they do take out ESU, so the argument of it "buying you more time" is completely incorrect for the majority of customers.

    HI ajp999 I understand the frustration. On Oct 14, 2025, Windows 10 will no longer be in support. Applying ESU to Windows 10 does not extend support nor does it extend the Windows 10 lifecycle. It allows for Windows Updates to be applied to the no-longer-supported operating system.

    All that said, installing Microsoft 365 Apps on in an unsupported configuration puts M365 Apps out of support. And having them installed on an out-of-support Windows 10 means it is not a supported configuration.

    You can see the support matrix here. If you have a Microsoft account team that you work with, I suggest that you bring this up to them to take further.
