SYMPTOMS
Free/Busy information from a foreign system such as Lotus
Notes or Novell GroupWise may not be available to users in Microsoft Exchange
2000 Server Service Pack 1 (SP1) or later. The foreign system client runs as
you expect on the Exchange server.
One known root cause is the
absence of the foreign system proxy address on the Exchange System mailbox. If
absence of the proxy address on the system mailbox is the problem, you will
observe normal functioning of the Exchange Calendar Connector when it is run in
console mode. You will see no errors even if the
mapical,
calsync,
notescal values are added to the
Providers subkey of the following registry key:
HKEY_LOCAL_MACHINE\System\Currentcontrolset\Services\MSExchangeCalCon\Parameters
If you increase the diagnostic logging level for
Calendar Connector to Maximum, the following information events may be logged
in the application event log: Event Type: Information
Event Source:
MSExchangeCalCon
Event Category: General
Event ID: 6001
Description:

RESOLUTION
To resolve this behavior,use one of the following methods
to add the appropriate proxy address to the MSExchange System Attendant.
Method One
The proxy address may be absent because of a behavior or conflict
in your recipient policies. For example, for Lotus Notes, make sure that you
click the Lotus Notes proxy address for a recipient policy that applies to
system attendant mailbox objects. The default policy will apply to the system
attendant.
Method Two
Warning If you use the ADSI Edit snap-in, the LDP utility, or any other
LDAP version 3 client, and you incorrectly modify the attributes of Active
Directory objects, you can cause serious problems. These problems may require
you to reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003,
Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows
and Exchange. Microsoft cannot guarantee that problems that occur if you
incorrectly modify Active Directory object attributes can be solved. Modify
these attributes at your own risk.
Although Microsoft does not recommend this method,
you can manually add the proxy address by using ADSI Edit, which is in
Microsoft Windows 2000 Support Tools. Make sure you have a System State backup
of your Active Directory before you try this procedure. After you start ADSI
Edit you must connect to a domain controller, browse to the following location,
and then click to expand the following object:
'CN=Microsoft System Attendant,CN=Your Server Name,CN=Servers,CN=Your Administrative Group,CN=Administrative Groups,CN=Your Organization Name,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=Your Domain,DC=com'
Right-click
System Attendant, click
Properties, in the
Select which Properties to View box the default is
Optional, click to change this default setting to
Both. In the
Select a Property to view box, locate the
proxyAddresses attribute, and then add the required proxy address (if the
required proxy address is absent).
If you connect your Calendar
Connector to Lotus Notes, the system attendant proxy address has the following
format:
NOTES: Microsoft System Attendant/Your Administrative Group/Exchange Organization Name@the Exchange Lotus Notes equivalent domain name
Note that the first proxy address (primary) must begin with
capital letters. For example, the first Lotus Notes address must begin by using
"NOTES:", and any secondary proxy addresses begin by using lower case letters,
such as "notes:".
