SharePoint Online Subsite Feature - Is it going to deprecate

Hi Team,

 

When will MS deprecate subsite feature from SPO? and what will happen to the existing subsites if deprecated?

Also, could you please share SPO roadmap for subsite.

Note that we are aware of flat structure and its recommendation from MS.

 

Thanks & Regards,

Shanthi.

    Has the ability to create subsites been removed? There was no announcement/notification, but I'm not seeing the option anymore.

      luuluu005​ , I can see the subsite creation option in my tenant, so it’s possible that your SharePoint admin has disabled subsite creation from the admin center.

      However, with modern SharePoint, I would strongly recommend avoiding subsites altogether and adopting a flat site architecture instead. It’s more scalable, easier to manage, and aligns with Microsoft’s current best practices.

    Microsoft has not announced a formal deprecation date for SharePoint Online subsites. Existing subsites will continue to function; however, the roadmap is clear with hub sites and associated hub relationships, the direction is toward flat structures for scalable, future‑proof governance

    Thanks for the response!

    Any idea when it will be removed? Or Is there any articles from MS about this deprecation? Please confirm.

      Microsoft haven't published a definite date or any documentation about this.

    My understanding is that the ability to create subsites will be removed but it won't affect already-existing subsites.
