Clean up your Gmail inbox

Disaster, you can no longer receive emails via your Gmail or Google Apps / G Suite mailbox? No error message on Microsoft Outlook, Thunderbird or on the phone (iPhone, Android)? The emails leave your application but you no longer receive anything? Do not panic, it is surely a problem of disk space which is filled. On free accounts, Gmail offers 15GB of space. A G Suite subscription (ex Google for Works and Google Apps) is 30GB per user. You can of course buy additional storage to have a quota of 100GB or 1TB.
