How to Fix Microsoft Outlook Failure to Activate License

When I upgraded to Windows 8 from Windows XP, everything worked well except Microsoft Outlook. It required me to activate its license and failed on every attempt I made at this. This may be due to it trying to write data to a folder that Windows 8’s enhanced security was blocking. Windows 7 users experience the same problem with Outlook’s license activation.

The solution is very simple. You need to run Outlook as an administrator, i.e. right click on the Outlook program icon and select “Run as administrator” from the list of options. Even though I was logged in as administrator, I still had to do this step to force Windows to run Outlook as an administrator. Outlook was then able to activate its license with Microsoft and then ran without a red title bar in the application that indicated a problem.

    I also do not have the option to run as admin. I have the red bar, but Outlook seems to be working so far, but only on certain email routers. Got the laptop in 2013, same as previous comment, updated from Windows 8 to Windows 8.1. Afraid to upgrade to Windows 10 due to all bad reviews.
