Sending, receiving, and organizing email in Outlook.com
Hi, I'm John! I will help you with this.
Just to clarify, are you using Outlook.com in a web browser, or the Outlook desktop/mobile app?
When you try to send an email, what exactly happens? Do you receive an error message or bounce-back notification? Does the email stay in Drafts? Does it appear in Sent Items but never reach the recipient?
Also, try sending a test email from Outlook on the web: https://outlook.live.com/mail Let me know how it goes.
Please share the exact result and any error message shown. That information can help determine whether the issue is related to the account, the app, the browser, or a temporary service problem.
