This assumes you already have an existing email account, and it's configured in Windows Mail.
Now let's learn how to setup Favorite folders.
In the left pane of Windows Mail you'll notice a section for Folders, under your account name.
This section only shows folders that are marked as Favorites. To see all our folders, click More.
Notice how some of the folders are marked with a star... these are marked as favorites, and therefore will show up in the left pane.
To mark additional folders as favorites, simply right click a folder name, then click Add to Favorites.
That's it! A star appears next to the folder name, and it also now shows up in our favorites section.
You can just as easily remove folders from the favorites area, by right clicking and selecting Remove from Favorites.
Please note that the folders listed here are mirrored copies of the folders, so anything you do with them in the Favorites section (like add or remove messages), will also happen in the folder's main location.
You can have as many folders in your favorites section as you like.
This is the end of the tutorial. You now know how to set up favorite folders in Windows Mail.
