I can not connect to marketplace because it needs windows live account and by outlook account does not connect.I think now is the end of wp7 and it does not connect is it true? thank you
The end of WP7 was in 2014. The marketplace no longer exists, which is why you cannot connect to it, even if you had an active Live account. You cannot set up a new Live account on a WP7 device any more either. You need a new phone.
