1094 Part XI: Upgrading and Migrating to SharePoint Products and Technologies
Tip Because of the width of the day, week, and month calendar view layouts,
the wider Top and Bottom zones are probably the most suitable for
displaying a calendar folder with the Page Viewer Web Part. However, using
the default setting in which the Web Part adjusts its height to fit the zone
might obscure the links at the top of the folder; these links allow the user to
switch between the day, week, and month views. Instead, experiment with a
fixed height to display those controls, as well as the link to create a new
appointment.
Tracking messages sent to a distribution list, such as a company announcements
list, is one practical example of using the Page Viewer Web Part with an
Exchange folder. Public folders can have e-mail addresses. If you include a public
folder among the members of a distribution list, all the messages sent to that list will
appear in the folder and, in turn, can appear in a Page Viewer Web Part.
Another application would be to display Exchange mailbox data using OWA
URLs for versions of Exchange earlier than Exchange 2003. (The Exchange Web
Parts that ship with SharePoint Portal Server 2003 work only with Exchange 2003.)
Creating an E-Mail-Enabled Document Library
Windows SharePoint Services supports the concept of an e-mail-enabled document
library, a document library linked with an Exchange 2000 or 2003 public
folder so that files attached to messages in that public folder are automatically copied
to a SharePoint library. Because Exchange public folders can be set up to allow
e-mail submissions, this provides a mechanism for both internal and external users
to submit documents to the SharePoint library without connecting to the document
library site itself or even having permissions to add documents to it.
This feature uses the SharePoint Timer service, which periodically checks the
public folder for new documents and copies them to the document library, creating
a document for each attachment and generating a unique file name by adding numbers
to the end of the file name if necessary. The service does not update, overwrite,
or delete existing documents in the document library and sets only minimal field values
for the document—the From address from the message, the subject line, and the
date and the time the document was inserted in the document library. Any additional
fields are left empty, even if they are required fields.
Setting up an e-mail-enabled document library requires configuration changes
on the server running SharePoint Portal Server at the virtual server level, plus
changes to the document library settings and the Exchange public folder settings.
