Hi @Gassan Elrayah

I understand how disruptive this is, especially when receiving works but outgoing messages fail. The error shown is generic, so one quick test should help identify where the problem is.

Please open Outlook.com in an InPrivate or Incognito window, sign in, and send a new plain-text email to yourself. Do not include a signature, attachment, or image.

If the test sends: the issue is likely related to the original message, attachment, signature, browser data, or the Outlook app.
If the test also failed: check Settings > General > Storage, because a full Microsoft cloud or mailbox allocation prevents sending. Also check whether the account has been temporarily restricted following unusual activity. Microsoft’s guidance additionally notes that Outlook.com will not send attachments larger than 25 MB. Review Microsoft’s official troubleshooting page.

If storage is available and the problem continues in a private browser, use Help > Still need help? within Outlook.com to submit the issue to Outlook.com Support. Forum moderators cannot inspect the account or server logs.

Please note that the @live.co.uk mailbox does not depend on a Microsoft 365 subscription. Any refund request is a separate billing matter and must be assessed by Microsoft Support under the applicable refund policy.

Thank you for your understanding

Hi @Ian-T - I have reviewed all the answers and followed all the instructions outlined. Still, getting the same error message when trying to send even just a text-only email.

Don't really have the time capacity to troubleshoot what should be a simple mailbox, so I just set up a new email address and will be phasing this one out... Maybe it's because it's a "Live.co.uk" email address perhaps?

Hi Gassan

Thank you for the update. I understand your decision, especially after the issue continued despite trying the suggested steps. I don't think the "live.co.uk" is the problem - there's maybe something with the server perhaps. You can try contacting Microsoft Support as well for further insight on this

I’m sorry the problem could not be resolved here, and I appreciate you taking the time to follow up. I hope the new email address works reliably for you.

Have a lovely day
