|Outlook will only look for an Exchange server if that's the type of account that's configured in Outlook. Once you install Outlook and run it, it will ask what type of account you wish to setup. If you're not on a work network, then you'd configure either a POP account, Internet Account, IMAP account, etc. depending on the type of account your friend is using. If you can at least open Outlook, go into the Account Settings and look at what's listed there. If an Exchange account is the only one, then add the correct account, set it as the default, and then you can delete the Exchange account.|
If you can't get into Outlook, go into Control Panel under the Mail option and look at the accounts listed. If it's 64-bit OS, you'll need to go into the 32-bit x86 Control Panel, then access Mail.
As for the printing issue, when your friend attempts to print, what is showing in the list of printers? If the AIO is set as the default in the Printers folder, then that's what should show up as default.
Just a note about the OS though, what was originally installed on the computer? Technically, if you installed an image from a business, then it's not really a legal license and your friend will eventually have invalid/activation problems. Just a thought...
