Hi dmurphy165,

I was going to just change the question title to encourage answers, and then send a private message, but decided to add a reply so that you get an email in case that is how you are following this.

See the help article Moving Thunderbird Data to a New Computer

Not too sure what you had on the old hard drive. Mozilla is not going to be storing your information. If it is a web mail account information may still be on the webserver.

What do you mean but lost the hard drive. Do you still have it and is it operational ? (For instance you are now using a new computer but have the old one)

I guess I'm just asking how do I log in to my Mozilla email account from a new computer? I have the same computer, but with a new hard drive.

Mozilla is not an email provider. You should be able to log on as before. Did you look at the article I linked to in my last post ? I presume you have already installed Thunderbird on the computer hard drive.

• If not then please see Installing Thunderbird on Windows

When you say you have Outlook on your computer are you referring to the outlook.com the webmail service or the outlook program Who provides your email service ? (Please do not state your full email address this is a public website )

• Outlook aka live.com & hotmail.com see https://wikipedia.org/wiki/Outlook.com
• Webmail see https://simple.wikipedia.org/wiki/Webmail
