Excel activate microsoft 365 but I do not want that -- current version Office 2021 (macOS)

Tony Oliver 0

I use an iMac. This morning, I used Excel as I do everyday. This morning, a pop-up appeared saying I needed to install Microsoft 365 but I do not want that. Word and Excel are both affected. I restarted the computer but the Word and Excel are still affected. Word help says "This product is no longer supported."

Moderator note: added info on current Office version to the title

I would also suggest that you submit a Problem Report on this issue to help ensure that Microsoft knows how many users are being affected.

There are some ongoing problems with the Office apps on an Apple Mac device at the moment.

1

What version of Microsoft Office do you have, is that a subscription to Microsoft 365 or a standalone version of Office like Office 2019, 2021 or 2024.

2

At the top left of your Mac desktop, click the Apple icon and select 'About this Mac', what version of MacOS is installed on your computer?

Office 2021, I think. But I cannot get at specific model reference because Word, Excel, etc is not working.

macOS Tahoe Version 26.7.1 is installed.
