I cannot open my PowerPoint file online.

Hi sracinez, Jacintha, are you still experiencing this issue at this time?

Jay yes I am

Still not working!

Does anyone know how to fix PowePoint blank screen?  I tried to open my PP file yesterday, but it began to show only blank screens, and I could no longer edit it - does anyone know the cure for this?

no error messages show up on Chrome. On Microsoft Bing I get the attached error message.

I am still facing the issue. Cannot open PowerPoint in dropbox. Restarted my laptop and did everything possible.

It looks like it may be a Microsoft issue based on the error codes but when I go to their status site, they aren't reflecting any outages.  Sure hope someone who knows something can help!!

I thought the same too. I have complained to Microsoft too sracinez Hope it will be solved soon! Double job for me now

I am still having an issue with this. Has this been resolved for anyone? Thanks!

I am still unable to access. I just got off of a chat with Microsoft. They are unable to resolve the issue. They say the problem is with Dropbox. Microsoft only supports OneDrive for online PowerPoint editing (and I was able to upload my file to OneDrive and edit it there with no problem) and told me to talk to Dropbox for help. Unfortunately, it's the weekend now, and Dropbox only has support Mon-Fri. 

At this point, it seems like the issue is Dropbox since it works fine on OneDrive.  Our team works in Dropbox, so hopefully this will be resolved soon. In the meantime, we have to work around it by downloading the file to edit offline and then uploading a new version back into Dropbox which is not optimal when several people are working on the same file in multiple steps of a project.
