# Microsoft 365 Account Blocked for Suspicious Activity? What to Do

Microsoft blocks accounts after risky sign-ins or spam sending. An admin should check the sign-in logs, reset the password, review inbox rules and two-step login, and then unblock the account.

Also searched as: account blocked Microsoft 365 · sign-in blocked suspicious activity · user restricted from sending email

- **Starting price:** From $300

- **Where:** Remote, anywhere in the U.S.

- **Quote:** Fixed price before work starts

## Try this first

- Have an admin check the user’s sign-in logs
- Reset the password and revoke sessions
- Check inbox rules and forwarding for anything unknown
- Turn on or reset two-step login
- Release sending restrictions in the admin center

Common causes

- A stolen password used from another location
- The account sent spam after a compromise
- Too many failed sign-in attempts
- Policies blocking risky sign-ins

## When it’s more than a quick fix

If the account sent spam or rules were added, treat it as a breach: other accounts and customers may be affected.

### How we fix it remotely

We investigate the sign-ins, secure and unblock the account, look for wider compromise and tighten sign-in policies.
