Google Workspace storage running low — what's actually using it

Large attachments in Gmail, big files and old versions in Drive, and Google Photos backups if enabled, are usually the biggest space users across a domain. The Admin console's storage reports show usage per user, so you can find and address the real culprits rather than guessing.

Coach's tip: check Google Photos backup settings specifically — many people don't realise their phone is quietly filling company storage with personal photos.
