Online office apps not working only showing It looks like the webpage at... might be having issues, or it may have moved permanently to a new web address.

Hi @Tamara-Hu ,

Having the same issue again and again for a month already.

Tried everything you have suggested

• incognito window
• clear cached files
• it's not related to a browser extension as after restart it works

The excel files opens only after a system reboot and for a limited time. In an hour or so files start to be unaccessible again. It's definitelly an issue which appeared in the latest month or so.

So you should report a widespread problem.

Why I have to restart the system every time I need to edit an excel file?

Online excel is broken. Just report a problem and engineers will fix it!

Update:

It's working in chrome browser, in an incognito window. So the issue can be related to Microsoft Edge browser.

Right at the same time it does not work in Edge, even in an incognito window.

Just before trying, cleaned cached files and images.

Going to switch to Google Workspace. Microsoft's support is the worst in the world.
