Start using your app for Office
The best way to fire up one of your apps for Office depends on which application you’re using (Word, Excel, etc...).
Start an app for Word, Excel, PowerPoint, or Project
If you’re using Word, Excel, or PowerPoint, click Insert > My Apps.
If you’re using Project, click Project > Apps for Office.
Double-click the app you want to use.
Start a dictionary app in Word
Right-click a word and then click Define.
Start an app for Outlook
Open an email message where your app is active.
For example, when you open an email message that has a street address, the Bing Maps app automatically appears in a gray bar near the top of the message.
Click the app name in the bar below the message header to open it.
