When users login to Office 365 (http://portal.office.com/)http://portal.office.com/
, they land inon their "SITES" page(https://company-my.sharepoint.com/personal/xxx_company_com/Social/Sites.aspx) https://company-my.sharepoint.com/personal/xxx_company_com/Social/Sites.aspx
by default.
How to change this so that users are redirected to a page in one of the collections?
