SharePoint Site Storage Limits
Hi I_NuB,I completely understand your question. While SharePoint defaults to assigning 25TB to each new site created with a Microsoft 365 Group or Teams, it is possible to set a custom storage limit (for example, 1TB or even 3GB) for each new site by modifying the settings in the SharePoint Admin Center.
You just need to go to:
SharePoint Admin Center → Settings → Site Creation → Set storage limits manually
There, you can define a default storage value (e.g., 1TB) so that new sites don't automatically get the full 25TB available.
I've attached a screenshot for reference.
Hope this helps, and feel free to ask if you need anything else!Thanks!
Hi I_NuB I haven't found such a setting. What I can suggest is using a script like this to identify sites using too much storage, and then manually adjust their limits from time to time. https://pnp.github.io/script-samples/spo-get-sharepoint-storage-currentquota/README.html?tabs=pnpps
Another approach would be to create your own provisioning process to generate sites with the desired settings.
