This article takes you through the steps needed to take for creating document libraries or lists.
Note: This can only be performed after incoming mail has been enabled.
1. Access your SharePoint site. Select Site Actions.
2. Create a new list or document library.
3. Select Document Library (in Example 1.) Give the list or document library a name as in example 2.
4. Select “Yes” to Allow this document library to receive e-mail.
5. Enter an alias for the list/library. For a document library it should be named something like “<customer domain_DocLibX>” (firstname.lastname@example.org).
Note: The alias will be an internal email address (i.e. email@example.com)
To prevent confusion this needs to be a strict naming convention and please understand this address will not be used to send to the Library and is only an internal address.
6. Create a contact using the Control Panel and use the Document Library address as the email address.
