Hi Kacie,
Welcome to Microsoft Community!
I understand that you are having the same issue of receiving spam emails that were sent from your account. Let me assist you with your concern. With this issue
we strongly recommend
that you attempt changing your password immediately. If you're done changing your password but still having the same issue, we recommend that you scan your computer for viruses and malware using a reliable
Antivirus product. Please visit the link below to know more about Microsoft's anti-virus:

There are some possibilities that there is a malware/virus downloaded to your computer, then gathers email addresses saved on your computer and sends itself out to all of those addresses.
Once your computer has been cleaned, immediately change your current password to a strong password. You may also need to check on the links below for additional information on how to protect your account from this
