Save your document to OneDrive so you can get to it from anywhere – at work, at home, or on the go. Or save to another location, like your desktop.
Go to File > Save As (or Save a Copy).
Select OneDrive so you can get to your document from anywhere.
Save personal files to OneDrive - Personal, and work files to your company OneDrive or SharePoint site. You can also save to another location in the list like This PC > Documents. Or select Browse to pick any location including the Desktop.
Enter a name, and select Save.
Note: When your document is stored in OneDrive, Word will save your changes automatically.
