In SharePoint Online, the storage space allocated to an organization is dynamically distributed among all sites within the tenant by default. As a SharePoint Administrator, you don’t have to worry about dividing up storage or adjusting allocations based on usage. This whole process is taken care of automatically: sites will use storage as needed without any manual interference.

There is a maximum limit of 25 terabytes (TB) of storage space that a single site collection can use. However, there is no hard limit on the total storage space used by all sites combined within a SharePoint Online tenant.
If a site collection reaches 25 TB, it goes into Read-Only mode until items are deleted from the site including the site’s Recycle Bins. If this limit is exceeded, additional storage may need to be purchased or the subscription plan may need to be upgraded -> Add more SharePoint storage to your subscription

Set Storage Limit on Sites
Modifying the storage limit of a site isn’t possible when the site storage limit setting is configured as ‘Automatic’. Admins have the option to specify reduced storage limits by changing the storage limit set to ‘Manual’.
- For this, go to Settings, in SharePoint Admin Center.
- Select Site storage limits, switch to Manual, and then select Save.
- You will now be able to regulate the storage limits for each site as per the requirement.
- To set storage limit for each site via PowerShell:
Set-SPOSite –Identity https://grandvm02.sharepoint.com/sites/TeamSite1 -StorageQuota 2048 -StorageQuotaWarningLevel 1500
This command updates the settings of site “https://grandvm02.sharepoint.com/sites/TeamSite1”. The storage quota is updated to 2048 megabytes (2 GB), and the storage quota warning level is updated to 1500 megabytes.
Storage Quota Warning on Sites
In addition to the warning message displayed at the top of the Sites, Site Admins and Site Owners will also receive email notifications regarding nearing or exceeding storage limits.
