SYMPTOMS

When you open the Microsoft Exchange 2000 Conferencing Service icon in Control Panel, the following error may appear in the Microsoft Windows 2000 application event log:
Event ID : 8212
Source : MSExchangeCONF
Category : Startup/Shutdown
Description:

The Microsoft Exchange Conference Management service could not log on to the Microsoft Exchange Information Store - idling until it can. Error code: 81002746; Message: /o=<Organization>/ou=<Administrative Group>/cn=<Recipients>/cn=<master mailbox alias>
Back to the top

CAUSE

Exchange Conferencing Service must successfully log on to the Site Conference Calendar Mailbox in the information store. If this mailbox is either unable to make contact; is hidden from the Exchange address lists, or has not been replicated to a global catalog server, a successful logon cannot be completed. Because of this inability to log on, the conferencing services are not provided.

Unable to Contact Mailbox

If you cannot contact the mailbox, check the following items:
  • Check the network connectivity between the conferencing server and the mailbox server on which the Site Conference mailbox is located.
  • Check the information store in which the Site Conference mailbox is located.
  • Check the mailbox store in which the Site Conference mailbox home is located.

Global Catalog Account Replication

  1. Use the Ldp.exe utility to verify the following Global Catalog attributes. The Ldp.exe utility can be found in the Windows 2000 Resource Kit:
    - DC=gonzoland,DC=com
    - CN=System
    - CN=Exchange
    - CN=Conferencing
  2. Verify that the Site Conference mailbox account is listed. If the account is not listed, replication between the Active Directory and the Global Catalog has not occurred. Subsequently, the conferencing service cannot find the account and is unable to log on.

    In this situation, you must wait for replication to occur before the conferencing service can logon to its Site Conferencing mailbox.
