The Upload Center is being replaced by the Files Needing Attention experience that will show up inside the Office applications under File > Open. This new experience is more modern, integrated, and less intrusive compared to the Upload Center.
What is the Upload Center?
The Upload Center is an application installed with Office where you can find Microsoft cloud files that are saved to your Office cache, including files that did not save to the cloud successfully. The most common reason why cloud files don’t save successfully is when you don't have internet connectivity.
Where should I go to find files that did not save successfully to the cloud?
You can go to File > Open > Files Needing Attention to find these files. The new Files Needing Attention section only appears if you have a file that didn't save successfully to the cloud.
Each app will show files for that specific app only, for example to find a Word file that did not save successfully, you will find them in Word. For Excel files, you'll find them in Excel, and so forth.
From Files Needing Attention, you can open the file and re-save, or, you can discard the changes completely.
What types of files show up in “Files Needing Attention”?
Files that appear here are files you've opened from the Microsoft cloud - OneDrive, SharePoint Online, or SharePoint Server - that you're not syncing to the local device. When such a file does not save successfully, for example if you disconnect from the internet after opening the file and subsequently make changes to it, the file will appear under Files Needing Attention.
You can also open the file from the Most Recently Used list under the File menu, click a link to the file, or open it like you normally would.
What versions of Office does this apply to?
The Files Needing Attention experience will be available in the Office 365 Monthly channel first beginning October 2019 and will be introduced in other versions of Office over time. We plan to replace the Upload Center completely by the end of 2019 for the Monthly channel customers.
For our Semi-Annual customers, this change is tentatively scheduled for the July 2020 release at the earliest.
Will I lose any functionality? Will there be any data loss?
What about the Delete Cache option in the Upload Center?
This option will now be under File > Options > Save > Cache Settings.
Will Admins be able to turn off Files Needing Attention?
Not at this time, no.
