Using subfolders in webmail takes some pre-planning. You need to consider how many levels of folders you need before you begin. Read through this entire article before trying the steps to see why.
Go to webmail.uvm.edu and login.
Click drop down arrow for Folder Actions in the left menu. Click New Folder.
Folders and the subfolder must be created at the same time; to do so type in the name of both folders as shown here:
If I would like to store all messages received in December in a subfolder, I would enter the following in the box pictured above:
received/Dec2011
The top folder, received can only store folders, the Dec2011 folder can store only messages.
If you want to further structure the filing strategy, enter all levels at from the start, for ex:
received/2011/Dec
This creates 2 layers: received is a folder that can only store folders, 2011 is a folder that can only store folders, Dec is a folder that can only store messages.
Click OK, you should see the new folders in the folder list. Click the [+] sign next to the folder to see the embedded folders within it.
To add more folders, follow the same steps, and enter additional folder names for the subfolders:
received/2011/Dec
received/2012/Jan
received/2012/Feb
etc.
