Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi ian mccarthy
Thanks for reaching out. I understand that you’re unable to send emails because your Outlook.com account has been temporarily blocked for “unusual activity,” even though you’ve only sent a small number of messages and are currently receiving a high volume of scam emails.
Have you already tried the Q&A Assist steps under your post?
In addition, please try the following steps:
1, Unblock your account
Go to Unblock my Outlook.com account – Microsoft Support and follow the guidance to complete the verification steps.
2, Avoiding sending limits
If you can unblock your Microsoft account:
- If there were several recent security or send attempts, a short time‑based lock may apply. Avoid repeated sign‑ins or sends for a while, then test again.
- Outlook.com enforces daily/recipient limits that vary by account history. If limits are reached, sending can pause. Sending limits in Outlook.com
- Review recent activity and update your password if prompted. This is part of Microsoft’s recommended recovery flow for unusual activity: What is the Recent activity page?
3, Reducing future blocks from scam mail
Blocking and reporting scam messages is correct, but it doesn’t immediately stop all new scams. Continue using “Report phishing” and consider adding trusted contacts to Safe Senders so legitimate replies aren’t filtered.
Please feel free to let me know how it goes. Thank you for your patience and understanding.
