Am a keen follower of Microsoft's SharePoint Blog and proud to provide this direct from the Microsoft Tech Community:

We’re excited to announce that we’ve started rolling out the ability for multiple authors to collaborate on SharePoint pages. Multiple authors will be able to edit the same page at the same time, without having to take turns. Authors can see real-time changes made by others as they happen in pages, sections, and web parts. 

After an author starts editing a page, they can see if other authors are also editing by viewing their avatar in the command bar.  Changes made by authors are saved automatically every few seconds. If authors want to leave edit mode, they can select Save and close. 

Version history has also been improved to enhance support for collaborative authoring. To undo more changes or changes made by other users, authors can restore a prior version from Version History (under Page details).

Frequently asked questions

When will this happen? 

We have begun rolling out to targeted release tenants and expect to complete by late July 2024. We expect general availability rollout to start in August.   

Track the feature status with Microsoft 365 Roadmap ID 124853. 

How will this affect your organization? 

Before this rollout, only one author can edit a page. While an author is editing the page no other user can edit until the author publishes or saves their draft.  

After this rollout, authors will have the ability to edit a page or news post while others are editing as well.  

What do you need to prepare? 

You do not need to do anything to prepare for this update, but you may want to let your authors know about this new capability.
