Sending, receiving, and organizing email in Outlook.com
Hi!
Are you able to send emails?
This issue often occurs when your email storage is full. If you have a Microsoft account, please check your storage by following the steps below:
- Open a web browser > Go to https://outlook.live.com/mail/options/accounts-category/storage > Sign in with your Microsoft account > Check whether your Microsoft storage and email storage are full.
- If you are not redirected to the storage page, from the main Outlook screen, click File > Settings > Account > Storage.
