To set up newsgroups for offline news reading

For newsgroups you subscribe to, you can set up Outlook Express to make
messages or headers available offline by synchronizing. This enables you
to read them at your leisure when you are not connected to the Internet.

From the Folders list, select a news server.
In the main window, select one or more newsgroups you subscribe to whose
messages you want to read offline. (To select multiple newsgroups, hold
down the CTRL key while you click the newsgroups.)
Click Settings, and then click to mark what you want transferred from
the server to your computer during synchronization: All Messages, New
Messages Only (new to the server since you last synchronized), or
Headers Only (subject, author, date, and size of message).
Make sure that the newsgroups you do not want to download are not
selected (Don't Synchronize).

Whenever you want to transfer the messages or headers to your computer
from the server, click Sync Account.

Note
If your online time is limited, you can target specific messages for
offline reading. For details, see Download individual messages.

The help file has additional information on this.

Hi All,
Under Tools it says "synchronize all" and "synchronize newsgroup".
What is the function or purpose of this?
Thanks, Mike
