If either your Outlook.com mailbox or your OneDrive storage is full, you cannot send or receive email. You have 5 GB of free cloud storage with your Microsoft account shared across your files and photos in OneDrive, attachments in Outlook.com and your Microsoft 365 apps. You also get 15 GB of free Outlook.com email storage which is separate from your Microsoft cloud storage.
What are the storage quotas?
Storage quotas are shown below:
| Subscription | Microsoft storage (cloud files) |
Outlook.com storage (email) |
|---|---|---|
| Free account (no subscription) | 5 GB | 15 GB |
| OneDrive | 50 GB | 15 GB |

| Microsoft 365 Personal | 1 TB (extendable up to 2 TB) | 100 GB |

You can check your storage usage and quotas in either OneDrive or Outlook.com
