Two PCs 1 phone cannot access Outlook, we were scammed and cryptic msges sent to all our contacts, since then no incoming mail at all

Incoming mail stopping completely after a scam and mass messages strongly suggests the Outlook.com / Microsoft account is either:

• Compromised or partially blocked, or
• Misconfigured (forwarding, rules, aliases), or
• Unable to receive mail because cloud storage is full.

A human cannot remotely “take over” the account for consumer Outlook.com the way a local tech might for a PC, but Microsoft provides specific tools and support paths.

Follow these steps in order:

1. Check account security and recover if hacked
   • Use the official guidance for a hacked or compromised Microsoft account: How to recover a hacked or compromised Microsoft account.
   • Step 1: On each PC and the phone, run a full antivirus/malware scan (or Windows Defender on Windows 10/11) before changing any passwords.
   • Step 2: Change or reset the Microsoft account password using the official password change/reset links.
   • Step 3: After regaining access, review account settings for tampering:
     • Connected accounts
     • Forwarding
     • Automatic replies Any malicious forwarding or rules can silently divert or delete incoming mail.
2. Verify Outlook.com can receive mail at all
   • Sign in to Outlook.com in a browser.
   • Confirm that Microsoft cloud storage is not full. If storage is full, Outlook.com cannot send or receive email and messages sent to the account while full are bounced and unrecoverable. Use the mailbox storage view linked from the Outlook.com article and delete or move items as needed.
   • If storage is fine but mail still does not arrive, check for error messages like “The recipient server did not accept our requests to connect.” If that appears, follow the guidance to update the email address/alias: Add or remove an email alias in Outlook.com.
3. Fix device sync issues (two PCs and one phone) If Outlook.com is receiving mail in the browser but not on devices:
   • Remove and re-add the Outlook.com account on each device.
   • For mobile, if sync issues persist, remove the phone partnership from Outlook on the web using the steps in “Fix email sync issues by removing a device from your Outlook mailbox.”
   • For Outlook mobile specifically, use the troubleshooting guidance in “Troubleshoot Outlook mobile issues” (covers sync and sign-in problems and deleting phone partnerships).
4. Get direct Microsoft support (human help) For consumer Outlook.com accounts, Microsoft support is available but is accessed through the web, not by remote control of the PC:
   • Sign in to Outlook.com in a browser.
   • Select Help on the menu bar and enter the problem (e.g., “hacked account no incoming mail”).
   • If self-help articles do not solve the issue, scroll down to Still need help? and select Yes to reach support options.
   • If sign-in is not possible, use the dedicated “can’t sign in” support link provided in the Outlook.com help articles.

If the account is a work or school Microsoft 365 account (not a personal Outlook.com address), contact the organization’s Microsoft 365 admin or technical support, as they control mail flow and security for those accounts.
