I have Office 2013 Pro installed on Windows 8 Pro x64. When I first did the installation new email notification would display as expected (pop-up with the new message title, and the envelope icon in the taskbar). However, now their work. The only way I can get the notifications to work is by running Outlook as an Administrator.
This is very annoying and I'd like to see if anyone has had a similar problem and what they have done to resolve it (if they have).
Thanks
Eric
