i can't see my contact list
I am seeing numerous recent reports of problems with contacts in New Outlook for Windows. e.g.:
1 -- Are you experiencing the same problem? If so, there does not appear to be an official acknowledgement of the problem from Microsoft and no fix that I have seen.
2 -- Are you using a Microsoft email account (e.g. one that ends with "@outlook.com". If so, can you see your contacts if you use Outlook Web? https://outlook.live.com/
but the contacts are still available for new mail
If you mean that you see suggested email addresses when typing on the "To:" line in a new email, I think what you are seeing are "Suggested people - Expanded suggestions". i.e. Outlook remembers email addresses your have sent to or received from in the past.
