Problem Sign in Outlook Classic

Copper Contributor

Can Anyone help?
I purchased a new laptop, run Windows 11, installed PC version Microsoft Office Suite and Outlook (new). I need to transfer many outlook data .pst files (emails, contacts calendar) from old computer to the new laptop. Learned from Microsoft Outlook Forum, I need to switch Outlook new to classic Outlook, then use File import to open outlook data files saved from old computer.
Although I have no problem launch and sign in Outlook new, I have problem sign in Outlook classic, error message is ”NOT NETWORK CONNECTION, Please check your network setting and try again [2604]”.  What does it mean and how to fix it?
