Macos Sequoia 15.0 and office 365 - not responding

what happens if you try to "save as" ? I too can open documents, but when I save as, it stalls out.

It Only works in the online Version. Not if you want to work in the local installation. Here ist works for some time and then it stops. The software does not connect to your profile in m365.

1. Don't use Office 365, use Keynote, Pages, iMovie, Garageband and Numbers.
2. Update the Office 365.
3. Reinstall the Office 365
4. Use Convertio to convert files.

Same problem here--on Office for Mac Version 16.89.1 and just upgraded for Sequoia 15.0. I get the spinning pinwheel when I try to open Word and PPT files. No difference if I open from the Finder or Word or PPT itself. Then have to force quit the Finder and/or Word or PPT and try again. Eventually it works but I cannot determine why or why not. Really frustrating as this is a basic function.

I have two laptops, a MacBook Pro M1 2021 and a MacBook Air M1 2020. Both have been upgraded to macOS Sequoia. While the Microsoft apps work perfectly on the MacBook Pro, they are completely unresponsive on the MacBook Air. I’ve tried deleting and reinstalling the apps twice, but the issue persists. It’s very frustrating.

Same here. it's very frustrating, can't open or save files, and it crashes every single time. basically can't do any work with this. Has anyone tried to "downgrade" to the previous macOS? I'm contemplating doing it.

I was just on a live chat with Microsoft about this problem. They told me to reinstall. I mentioned this and other forums, and that reinstalls were not solving the problem. The response was essentially that it was the fault of Apple. I mentioned that perhaps they needed an update of their own to be compatible. I was told that because Apple has a closed system, there are often compatibility issues with Macs. Here's an idea: disclose that when you're asking people to pay for a Microsoft 365 subscription. We ended the chat with the rep telling me that now that they are aware of the problem, they will look for a speedy solution.

I used to Use Office 2016 permanent license products and use perfectly, unit with Sequoia 15.0,

After that .docx and .xlsx files became idle.

When I try to ask, "please choose app" notification pop-up.

I felt like 2016 in not compatible with Sequoia 15.0.

I bought Office 2021 permanent license

Deleted 2016 and installed 2021.

Still same, nothing changed.

I still can't open .docx and .xlsx intention files.

.ppt is working interestingly.

I send complaint to Office support desk.

No reply.

But the issue is persisting with the 15.0 stable release. The only thing that makes Office 365 (web) manageable is using the 'icon' view, everything else is just a blank page. Constant reloading after I click a link to open the link.

It is only an issue in Safari for me. Using Office 365 (web) with Firefox, everything works fine.

Same issue still persists for me as well. I can open documents, but cannot save or save as or even close down the application other than forcing it to stop. I saw an update for Sequoia 15.0 run this morning, so I thought it would be a patch, but the issue is still there, I have reinstalled the full OFC365 for Business package again, still no joy.

My question is this: does the Apple software developer team not test these out - does the fact that the majority of business users use OFC365 not give it enough weight for proper beta testing before rolling out a new OS version?

Sounds like the usual infuriating level of unhelpful feedback from "support".

The fault absolutely cannot possibly lie with Microsoft not ensuring that their flagship product for MacOS runs on the preview developer previews of Sequoia or indeed the production version of the new OS. No, no no...

What an arrogant response...

Safari v18, definitely "breaks" O365 online...on the other hand, Teams online, has been in "Preview" mode for Safari, for years, many years.???

Oddly, Google's online app get along well with Sequoia / Safari 18.???

Microsoft is pushing Microsoft Edge, Bing and Copilot...coincidence? If you want seamless compatibility with O365 online, use Microsoft's Edge browser.

Thanks, but a lot of us have tried this without success.

Similarly for the suggestion to do a factory reset - like setting up a new user account but even more of a pain eg what do you restore from - if it's a Time Machine backup you run the risk of reinstalling the same problem since no-one seems to know what causes the problem.

I'm not familiar enough with Terminal so can someone tell me if running these commands could also affect the new user account I set up where I'm not having the same problem? I'd hate to do this only to discover that one had somehow got "infected" too.

And are these separate commands to be run sequentially or do I just paste the entire set into Terminal?

Thanks

I tried running those Terminal commands, but unfortunately, they didn’t work for me. The issue persisted, and I still had to go through the factory reset to get Office 365 to function properly. Thanks for the suggestion, though!
