If you’ve already installed Yesware for Outlook via www.yesware.com/install, please follow the following steps in order to locate Yesware in Outlook Web Access (sometimes referred to as the Web App).

1.) Single-click any email so that it previews on the right hand side
2.) Click the three horizontal dots on the top right of the previewed message - labeled “More actions” when hovered over. 

3.) Scroll down to “Yesware” > Click “Open Yesware”

4.) When the sidebar opens, click the push pin icon on the top right to pin the sidebar to your Outlook so you don't have to go digging for it every time.
