My account has a license to Office 365 Small Business Premium. I have this account activated on 2 devices (both Windows 7 with Office 2013 installations). I wanted to try Outlook 2013 on my MacBook Air with OSX 10.9.5. I used the installation download option from my Office 365 software download page.
When I try to activate Outlook, I receive the error message "We couldn't find a subscription connected to your account." Really? Then how is it that I am using this account for 2 other PCs? What am I doing wrong?
