Overview of Co-authoring in SharePoint Online
Microsoft provides a lot of features to work with documents in SharePoint Online. One of the most useful features is co-authoring documents. By using this feature, we can collaborate with multiple users at any time, without interfering with each other’s changes.
Also, it is easier to use from the end user’s point of view. Suppose, if you want to work on a document library in Word, Excel, PowerPoint, OneNote, or any office web app then you can use this co-authoring feature to collaborate with multiple users.
Here, consider the below points to use co-authoring in SharePoint Online. Such as:
- Make sure the users should have edit permission for the SharePoint document library. Then, only users can work on a document library.
- We can use versioning to keep track of all changes in a document library, while users are editing the documents.
- When the user checks out a document library for editing, the document is locked. That’s why don’t enable the “Required Check-Out” feature.
- If you want to disable the co-authoring feature, then enable the Required Check Out feature under the versioning settings in a SharePoint document library.
