I tried to set up Windows Outlook and inserted wrong information for server. I didn't realise it would be so hard to change the information afterwards so I just gave it a go (I wasn't sure what the server was).

I just bought a new computer and MS home premium 365 for it. On my old computer, I was using Mozilla Thunderbird. Now, I wanted to use my old email address and start using Outlook, and import all my information from Mozilla Thunderbird, which I used before. That's when I entered the server information onto Outlook. I thought I could just try it and there would be no risk. But I was very wrong. Now I can't access outlook and so I cannot change the settings either. I don't know what to do. I also already set up a new gmail because I thought it would be easier to start using a new email address with Outlook. But now I'm completely stuck and cannot do anything. Please help... I really want to use Outlook both on my new computer as well as my phone. But I can't even open it.

The error message I get is: We're sorry but Outlook has run into an error that is preventing it from working correctly. Outlook will need to be closed as a result. Would you like us to repair now?

I get this message when I try to open Outlook. So I can't even open it. I have also tried to click on 'repair now' but that didn't change anything.

I have also tried to access outlook.exe /resetnavpane but I get the same error message.

Should I uninstall Outlook and then reinstall it, or will I run into additionalk problems if I do that?

I would really appreciate some help...Thank you.
