Ukrainian is a fully supported display language for Microsoft 365/Office on Windows desktop, but language availability differs by platform and product. The documented language list that includes Ukrainian applies to Office 2021 and Microsoft 365 for Windows, not specifically to macOS.
For Windows desktop, Ukrainian is listed as one of the available display languages for Office 2021 and Microsoft 365 subscriptions:
- “Ukrainian” appears in the supported display languages list for Office on Windows.
However, the context provided only documents language availability for:
- Office 2021 and Microsoft 365 on Windows desktop, and
- Office enterprise web/admin experiences,
- Microsoft 365 Copilot prompts and responses,
not for Microsoft 365 apps on macOS.
Because language support is platform-specific, the fact that Ukrainian is supported on Windows and in Microsoft 365 Copilot does not guarantee that the same language is available as a display language in the macOS version of Microsoft 365 apps. The absence of Ukrainian in the macOS language picker indicates that the macOS build currently does not offer Ukrainian as a UI/display language, even though it is supported on other platforms.
In short: Ukrainian is supported as a display language for Office on Windows and as a prompt/response language in Microsoft 365 Copilot, but the available documentation does not list macOS language support, and the behavior observed (missing in macOS) is consistent with platform-specific language gaps.
