The Microsoft Office Upload Center was a new feature added to Office 2010 and still available in Office 2013 and 2016. It allows you to manage documents you upload to OneDrive. If you upload a lot of documents at a time, this can be a helpful tool.
However, if you don’t upload many documents at a time or at all, you can remove it from the notification area on the Taskbar. It’s simply a matter of changing a setting in the Upload Center.
To remove the Microsoft Office Upload Center from the Notification area, right-click on the Office Upload Center icon and select “Settings” from the popup menu.
NOTE: You can also access the Office Upload Center from the Start menu by selecting “All Apps” and then under “Microsoft Office 2016 Tools”. In Office 2013, the Office Upload Center is under the “Microsoft Office 2013” group with the other Office apps.
In the “Upload Center”, click “Settings” on the toolbar at the top of the window.
The “Microsoft Office Upload Center Settings” dialog box displays. In the “Display Options” section, select the “Display icon in notification area” check box so there is NO check mark in the box. Click “OK” to accept the change and close the dialog box.
To close the Upload Center, click the “X” in the upper-right corner of the window.
Remember, even if you remove the Office Upload Center from the notification area, you can still access it using the Start menu. Find out more information about the Microsoft Office Upload Center here.
