Hi guys. So i have tried everything that you said, also what microsoft aupport said including office reinstall and ios reinstall, nothing worked. Then i went to microsoft autoupdate -> advanced-> update channel choose “beta channel” and there you have it :) it works

Dear all

I try all I reinstalled my brand new MacBook Pro m4 max 2 times and it came again that excel, powerpoint and outlook some times freeze.

Then I did this what helped me so far and it works now all fine:

2. Reset Launch Services:

• Open Terminal and execute the following commands to reset Launch Services, which can resolve application association issues:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network

killall Dock

3. Clear Office Font Cache:

• Corrupted font caches can cause Office applications to hang. To clear the font cache:

• Open Terminal.

• Navigate to the Office font cache directory:

cd ~/Library/Group\ Containers/UBF8T346G9.Office/

• Remove the font cache:

rm -fr FontCache

• Restart the Office application.

4. Delete Notification Temp Folder:

• If you’ve updated to macOS 15.1 and are experiencing issues with applications hanging, deleting the notification temp folder may help:

• Navigate to the following directory:

~/Library/Group Containers/group.com.apple.UserNotifications/Library/UserNotifications/Remote/default

• Delete all contents within this folder.

I hope it helps someone else as it worked for me. Not sure when I need to re do it again hope Microsoft Apple will fix that issue soon.

Cheers all

Problem solved , install a new copy of Sequoia 15.01 this morning , and first , the widgets are back, and then excel, Power point and Word, works just fine, it takes me a couple of hours, a pen drive with sequoia 15.01 installer and the problems was solved by me , without the support of Microsoft ( they don´t care about this issue ), hope you guys solved this issue with my recommendation

This was happening to me as well. Created a new user and attempted to open Word and Excel using the new login. Both products worked. Logged back in as old user. Open Terminal > cd /Users/<username>/Library/Group Containers/UBF8T346G9.Office/

rm -fr FontCache 

Opened Word successfully

You can also access this through Finder for those more comfortable with the GUI. Users/<username>/Library/Group Containers/UBF8T346G9.Office/

I found several corrupted DB files for a user and trashed them. Now Save and Save As work as expected. The user was having the same issue with Word, Excel, etc.

This worked for me: Open the Terminal and run the following commands:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user 

sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network

killall Dock

for me this solution worked : sequoia notification center not working o… - Apple Community

Navigate to

`~/Library/Group Containers/group.com.apple.UserNotifications/Library/UserNotifications/Remote/default`

There delete everything inside

This worked for me: Open the Terminal and run the following commands:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user 

sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network

Same problem. I was fine until I installed the .0.1 version.

However, I did set up a new user account and everything is fine there, so I wonder if it really is a general compatibility issue with Sequoia/O365 or some file or process that wasn't replicated when I created the new user.

I had the same issue - I deleted and reinstalled, created new users as well as all other suggestions. Finally, I went to the Genius bar and they told me to turn off Auto Save in Excel. In Word, uncheck ALL option in Save Options, and restart the computer. It has been 2 weeks and it appears to be working ok.

This worked for me: Open the Terminal and run the following commands:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user 

sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network

killall Dock

Search Terminal in Mac and

This worked for me: Open the Terminal and run the following commands:

enter below 2 lines and click enter

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user 

Now enter below 2 lines and click enter, Let it run 2 mins and quit terminal it will fix issue

sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network

How I Fixed It

Since upgrading to macOS Sequoia (15.0.1), I’ve been facing issues with Microsoft Office 365 (version 16.89). Every time I tried opening a Word, Excel, the application wouldn’t respond, forcing me to quit and restart it. After reinstalling Office multiple times without any luck, I finally found a solution: resetting macOS to factory settings.

To fix the issue, I went to Settings > General > Transfer or Reset, and did a full reset. After that, Office 365 began working as expected, allowing me to open and work on files without freezing.

This process solved the problem for me, so if anyone else is facing similar issues, it might be worth a try!
