Hi @Ajaz Khan ,
Based on your description, there may be some data that is not being properly accounted for in the storage calculation. For example, if there are large files or deleted items that have not been purged, they could be taking up space in the storage allocation.
To investigate further, you can try the following steps:
- Check the storage usage for each individual site collection in SharePoint to see if there are any large files or deleted items that may be taking up space.
- Check the storage usage for other applications or services in your tenant to see if they are using any of the allocated storage.
