There are three folders types: Mail, Address Book, and Notes. They are used to store email, contacts and notes respectively.
The main folder where email is received is called the InBox. You can add folders for a variety of reasons: storing email for later reference, keeping copies of email you send, managing contacts and tasks, etc.
Be aware, however, that each user has a storage limit.
Note that a folder can have sub-folders.
The InBox is the folder that is analogous to the box outside your home which is regularly visited by your friendly mailman. All mail is delivered to the InBox. You shouldn't keep every mail message you receive in your InBox. After you've read and dealt with an email, delete it or move it to another folder.
POP mail clients will only retrieve mail that
is currently in the InBox.
The Trash Can is a folder that is created to
hold deleted email messages. Unless you
change the way your email is deleted, email
will stay in the Trash Can until you logout and the email has been in
the trash for at least 24 hours. You can force your Trash Can to be
emptied immediately by clicking on Empty Trash.
If you use a slash ("/") in the middle of a
folder name, it will be defined as a sub-folder.
Any folder which includes a slash ("/") in the middle its name is considered a sub-folder. The purpose of sub-folders is to group folders together. They can be deleted and renamed as a group.
Normally you will first create a parent folder which will include the sub-folders as shown in the following example.
Note that caution should be used when deleting or
renaming a parent folder. By default when a
folder which includes a slash ("/")
is deleted or renamed, its
sub-folders will also be deleted or
Yes. You can share a folder you create in the WebMail interface with another WebMail user.
The other user can then follow the
instructions to see a folder you have given them access to?
Yes. Although I'm not sure why that would be helpful. The main reason I'm answering the question is in case some of your folders disappear from your WebMail.
If you set All Account Folders (Settings - General) to No and
All Subscribed Folders (Settings - General) to Yes, then you will
only see the folders listed for Folder Subscription
Yes, there are storage limitations on your email account. If your allotted storage is used, email sent to your account will be rejected. The amount of storage used is listed with the folders.
