To all,
My company purhased Microsoft Outlook 2010. I had trial version on my computer that had expired. When I copy/pasted the Product Key (OEM), it went through the installation process but only Business Contact Manager was installed and not Microsoft Outlook 2010 (Calendar, Mail, Tasks).
We purchased through Amazon.com. I first downloaded directly from the link. (I was sent a copy of order via email from my company which had product key.) I also tried to copy/paste product key into the trial upgrade box but the Microsoft said it was not a valid product key.
I have a receipt of payment from Amazon with Product Key.
