I know that running 0365 apps on Terminal Server 2019 (RDP) will no longer be 'supported' beyond Oct 2025 but what exactly is meant by 'supported' .

Will it:

A: Immediately cease to function.

B: Keep working but with no feature or security updates (obviously not something we want to do for long !).

Migrating to Server 2025 will buy us more time, but I would still like to know exactly what this 'end of support' means.

    It is covered in their official documentation here. Specifically the big blue box at the top of the article. Note that what is technically going out of support is the server OS. Since the server OS won't be supported anymore then software that runs on it won't be formally supported either.

    Going out of support means that MS will no longer provide support should you run into issues. They will no longer worry about the unsupported OS version when adding new features so a future update may stop working on unsupported OSes or not install at all. This goes for the OS as well because Server 2019 is end of main stream support already.

    So, you can continue to use the software after the given date. It won't just stop working. However future updates may start using features that it doesn't support. Nor will you receive any support if things stop working.

    Hi,

    When Microsoft says that Office 365 apps will no longer be supported on Windows Server 2019 (RDP) beyond October 2025, it means that after this date, Microsoft will no longer provide:

    Technical Support: You won't be able to get help from Microsoft for any issues related to Office 365 apps on this platform.

    Security Updates: There will be no more security patches or updates, which could leave your system vulnerable to security risks.

    Bug Fixes: Any bugs or issues that arise will not be addressed by Microsoft.

    This change encourages users to migrate to newer platforms or alternative solutions, such as using Office 365 apps on supported operating systems or considering cloud-based solutions like Azure Virtual Desktop.

    Hope the information is helpful.
