Just updated my M3 MacBook Pro max to the new Tahoe - but now none of my Microsoft apps (Word, Excel etc fail to work). I've since binned these, re-purchased a new 365 subscription today and downloaded / installed and updated all apps, but no - they quit as soon as I open them. Anyone else having this? Currently I'm stuck..

I had the same issue. I contacted apple support, here was their solution: Restart Mac in Safe Mode, relaunch the Apps. If trouble free, then restart again in Normal mode. Safe mode clears the caches and performs systems checks that seems to have resolved the problem for me.
I have run Office 2021 for Mac Home and Business and now Office 2024 Home on my M4 Mac Mini Pro with Tahoe 26.0.1 and I have absolutely no issues with these applications or their licensing.
Current application versions are 16.102.1.
Zelfde probleem hier. Ben er we een beetje zat van dat de updates zo slecht zijn dat er vaak iets stuk gaat. Tijdje geleden pakte MS Outlook na een update van Apple opeens de automatische adressering niet meer. Meer dan een dag tijd verloren!! Drie dagen later kwam er een nieuwe update waardoor het wel weer vanzelf werkte. Fout zit dus duidelijk bij Apple.
I'm glad I could help. There's nothing more frustrating than not being able to use your documents. And microsoft stopped it's online and phone support for about a week. Equally frustrating and so unprofessional! Probably got swamped with Mac users! Can't somebody think in advance for once?
Hi
I have the same issue with PowerPoint after upgrading my iMac from Sonoma 14.7.4 to Tahoe 26.1. Word, Excel and other MS 365 apps work but not PowerPoint. MS 365 version I have is 16.103.4 (25120717).
My PowerPoint behaves differently - when I double click on any ppt file it gets loaded BUT it does not display on the screen. The only way I can view the loaded ppt file is when I do a select View followed by Enter Full Screen from the PowerPoint Menu bar.
I have tested using Safe Mode and it works perfectly fine under Safe Mode - no issues.
I have logon to another user id on the same iMac and works perfectly fine - no issues
I have uninstall and re-install MS 365 the issue still persist. I have also deleted the the necessary files in the library, containers, group containers etc as suggested in the forum - nothing works.
I even downloaded the MS365 from the App Store as someone suggested might work.- same issue still persist in my case.
Since it is a common problem after the upgrade to Tahoe - I thought Apple would do something about this and give a solution to resolve this inconvenient issue.
Does anybody have any solution that I can try? Please need steps.
The only issue I have is in my primary user id.
This all happened after the upgrade to MacOs Tahoe 26.1!
Help!!!!
I have the same issue. I tried the method above, restarting in Safe Mode, opening all the apps, which worked fine (in Safe mode). Restarted in normal mode, and the issue still persists.
The apps won't even open so there is no way to get to "get info."
It is not a universal issue. My Mac has no issues:
Yes I'm still stuck - basically, the apps do work, but I cannot do the auto updates as this then causes the issue.
I've tried all the tips / open with Rosetta etc. but still need a fix.
Ninguna app se abre, todo deja de funcionar aunque intente usar Rosetta.
Thank you chiinagal13. This fixed the issue for me. I was all set to purchase a new subscription to office when all the other suggestions failed. Thanks for taking the time to post.
@chinagal13 looks like this has finally fixed my issues - thank you kindly..!! Currently updating...
