Hello.
According to my search, Microsoft 365 apps are available on Windows 11 Enterprise LTSC version.
The GAC version is the standard enterprise edition of Windows 11 and includes all the latest features and security updates.
The LTSC version, on the other hand, focuses on long-term stability with less frequent updates, mainly security and critical fixes.
As a result, compatibility testing on the GAC version may not fully cover the scope of compatibility checking on the LTSC version, as the frequency of updates and feature sets differ between the two.
Please refer to this link for more information:
