So currently I’m trying out the public beta of Office 2013, which can be found here
And when I started Outlook 2013 and went to my Calendar pane, I saw this little bar predicting the weather.
This is connected to Microsofts weather service also used in Windows Phone 7, 8 and Windows 8.
By hovering over it, we even receive even more detailed weather predictions:
Because the preview version of Office 2013 is in English my weather forecast was shown in Fahrenheit instead of Celsius. This can be adjusted in the Outlook options.
Click on “File > Options”, and then select the Calendar pane. Scroll down..
..and select Celsius, now click OK.
Et voilà! Celsius degrees in Outlook 2013!
