win 10 People folder not syncing to my log in for Outlook contacts

My wife and I use office 365 ( or Microsoft 365 today) .. and because she is logged in to our 365 together ( five members )  I cannot use my people folder for address's are all hers .. )  even though we are on two computers and two logins ..  i I log off the 365  I cannot use the program with out being told to buy today .. 

My outlook 2016 email program  works fine in my emails etc. .. but my address book is entirely hers .

Do I really have to to Hotmail to do this ?

Ideas ??
