Hello Neringa Petrosiute,
Since the same error occurs with both verified aliases, and the standard alias-management steps provided by AI have already been tried, there may be an account-specific issue that cannot be diagnosed from the community forum.
Please do not remove the Outlook.com alias while testing, as removing a Microsoft-owned alias may permanently delete that address.
