If you use Microsoft Outlook Web Access (OWA) to post messages to a newsgroup folder when the Network News Transfer Protocol (NNTP) service is not running, the messages that you posted may not be visible to the NNTP client after the NNTP service is started.
To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:

The English version of this fix should have the following file attributes or later:
Component: Information store
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server. This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 3.
After you install this fix, you have to rebuild the newsgroup folder. This makes the messages that you posted to the newsgroup folder (when the NNTP service was stopped) visible to the NNTP client. To rebuild the newsgroup folder:
Start Exchange System Manager.
Expand the server_name object, expand the Protocols object, and then expand the NNTP object. Expand the default NNTP server, and then stop the NNTP server.
Click the default NNTP virtual server, right-click the default NNTP virtual server, click All Tasks, and then click Rebuild Server.
The time that it takes to rebuild the server is based on the number of items in the newsgroup folders. Therefore, rebuild the newsgroup folder after ordinary business hours.
