If your Microsoft account has been compromised, it means that someone might be using your account to access your personal info or send spam. Such info could include emails, contacts, and photos from Outlook.com and OneDrive. It could also include your health data if you have connected services like HealthVault. Use this guide to get back into your account, review your personal info and settings, and help prevent this from happening again.Why was my account blocked?
We noticed unusual activity in your account, so we temporarily blocked it. We know that having your account blocked can be frustrating, but it’s an import tool to help us protect all of our customers, including you, from junk email and online fraud.
If you think your Microsoft account has been compromised, try to sign in to it online. (If you're already signed in on your device, sign out first.)
If someone else got into your account, you want to make sure they didn't use your data or change your settings. Sometimes attackers make back doors into your account so they can still see your information after you reset your password. Use the following steps to review your important settings.
Take a look at our tips in Help protect your Microsoft account. We especially recommend you take a look at our Do’s and Don’ts for creating a strong password, and then add security info to your account. Adding security info can make it easier to recover your account if someone else takes control of it, or you forget your password. Because this info is used for your safety, it's a good idea to add as much info as you can. We never use your security info for marketing purposes—it’s only to verify your identity.
