To allow others to contribute to your file--perhaps a sign-up sheet or shared project--you can share a link to it that allows editing. When you access the document stored in OneDrive, you can choose Get a link and set the permission to Edit. Then anyone who gets the link can edit without having to sign in.Â
Important:Â If more secure file access is needed, see Sharing private docs below.Â
Initiate the share Â
-
With the file open in Word for the web, Excel for the web, PowerPoint for the web, or OneNote for the web, go to Share.
-
Select Share > Copy link to share it.
When others click the link, they will go to the document. They can then start editing by clicking Edit in Browser. If you happen to be in the document at the same time, you'll see them listed as Guest.
They will be able to work in the browser without signing in. However, they will need to sign in with a Microsoft account to have access to certain features such as inserting a picture or using their Office desktop program.Â
Stop sharingÂ
You can stop others from editing your doc by selecting Share > Manage access, then remove the sharing link to stop access.
Sharing private docs
When you're working on sensitive information, you likely want to be careful about who can edit the document. Instead of sharing a link, you can invite specific people to sign in with their Microsoft account to view or edit the document.Â
-
With the document open in Word for the web, Excel for the web, PowerPoint for the web, or OneNote for the web, go to Share and enter the person's email address in the To box.
-
In Link settings, choose Edit (or another permission), then select Copy link to share it.
