Sending, receiving, and organizing email in Outlook.com
To help narrow down the issue:
- Can you share what made you think the accounts were hacked?
- Does it look like the email address linked to your account was changed?
- Did you receive any alerts, notice unusual activity, or received any notice that your security info was changed (email/phone updated)?
If you are currently traveling, some sign-in attempts and security alerts may be triggered because Microsoft detects a new location, device, or network. In some cases, these alerts can be related to your own activity rather than an unauthorized person accessing the account.
If the issue persists, please provide more details by answering my questions.
