Outlook 2010 problem (new member)

[Cullers]

Hi guys
Just joined the forum and hope to be a regular.

I recently had a disaster with my laptop. I was running Vista but have now upgraded to Windows 7 (x64) and am using Office 2010.

I didn't get chance to export my outlook settings properly and so have lost two or three of my email accounts from the accounts section of Outlook. I have managed to recoup the main account but I had a mail account with a provider who no longer exists (however the email provision still is available). I have absolutely no idea what the account details were (they were unchanged for three years) and the company hosting it now will (or can) not provide details. How do I find and implement the previous outlook accounts (not just the emails but the account (server settings, password, etc))?

Cheers for any help you can provide guys!
