Office 2019 Mac Upgrade: Switch to Office 2024 Before 13 July 2026

A classic Office 2019 Mac upgrade in the sense of an in-place update doesn't exist — the switch is a new purchase of Office 2024 Standard for Mac as a one-time purchase. The reason is 13 July 2026: on this deadline the code-signing certificate for Office 2019 for Mac expires and is not renewed by Microsoft. Word, Excel, PowerPoint and Outlook will still launch afterwards, but can only be used for reading, viewing and printing — editing and saving is then no longer possible.

What Happens to Office 2019 for Mac on 13 July 2026

On 13 July 2026 the certificate used to sign Office 2019 for Mac expires. Microsoft is not renewing this certificate. The consequence: the apps still open, but switch to a pure read mode.

• Word, Excel, PowerPoint and Outlook still launch — they are not blocked.
• You can open, view and print documents.
• Editing and saving is no longer possible from the deadline onwards.
• Office 2019 for Mac already left mainstream support on 10 October 2023.
• A non-updated Office 2021 for Mac is also affected. An updated 2021 (version 16.83 or newer) is safe for now.

Why Office 2024 Standard for Mac Is the Solution

Office 2024 Standard for Mac is a one-time purchase with a perpetual licence — no subscription and no recurring costs. You get Word, Excel, PowerPoint and Outlook and keep working without read-mode restrictions. The licence has no expiry date; security updates are provided within the Microsoft lifecycle.

• One-time purchase instead of a subscription — perpetual licence with no expiry date.
• Includes Word, Excel, PowerPoint and Outlook.
• Microsoft-signed and immediately available via download.
• Runs on Apple silicon Macs (M series) and Intel Macs.

Office 2019 for Mac and Office 2024 Standard Compared

If you only need the classic Office programs on your Mac and don't want a subscription, the one-time purchase of Office 2024 Standard is the right way to go.

Does Office 2024 Run on Your Mac?

Office 2024 Standard for Mac is designed for current macOS versions and supports both Mac architectures. Before switching, it's worth taking a quick look at these points:

• Obtain Office 2024 Standard for Mac via download.
• Install it on your Mac with the Microsoft-signed installer.
