Using New Outlook on Windows for personal email, calendar, and contact management
Hello. I’m sorry this happened to your account; I know situations like this are frustrating and disruptive.
Were you able to recover and secure the account successfully?
Regarding your contacts being called, that activity is consistent with a security breach. As a precaution, it would be advisable to inform your contacts so they are aware of the situation and can ignore or report any unexpected messages or calls that may have come from the compromised account.
