SYMPTOMS
When users perform free and busy queries from Exchange Server 5.5 Service Pack 3 to Novell GroupWise 5.x across the Exchange Calendar Connector, the queries may not return the free and busy results for the GroupWise user. If you set diagnostic logging to maximum, Windows NT Event Viewer displays several 6001 event messages. Some of the event messages contain the following descriptions:

Event ID: 6001

Source: MSExchangeCalCon

Type: Informational

Description: Unable to find Requestor in Directory.

Event ID: 6001

Source: MSExchangeCalCon

Type: Informational

Description: HrProcessNext Transaction Failed.

When Exchange users perform free and busy queries to Novell GroupWise or Lotus Notes by using the Microsoft Exchange Calendar Connector, the queries do not return the results for the foreign user. In Microsoft Outlook, the foreign users' calendars appear empty, as if there is no data in their calendars on the foreign system. This occurs because Calendar Connector Synchronization created the foreign user's objects in the Schedule+Free/Busy folder, but no data is populated for that user.

Note You can verify this by using the Mdbvu32.exe or equivalent utility to log into the Schedule+Free/Busy folder, and then make sure that the foreign user's UID is in this folder.



CAUSE
This issue may occur if the system attendant does not have a GroupWise address. This issue may also occur if the Microsoft System Attendant mailbox does not have a foreign address, such as GWISE or NOTES. One possible reason for this in Exchange 2000 is that the foreign address (GWISE or NOTES) has not been selected in the Default Recipient Policy, but there may be other causes.



RESOLUTION
To resolve this issue in Exchange Server, follow these steps:  In the Exchange Server Administrator program, open the system attendant properties, click Server, and then click Server Name. Click Private Information Store, click Mailbox Resources, and then add a GroupWise address. To use the proper GroupWise address format, use an Exchange Server user to obtain the correct GroupWise domain and post office, and then use the name of the Exchange Server system attendant for the name, for example:

gwise:{. . - .... . .exchange-



To resolve this issue in Exchange 2000, the foreign proxy address must be manually added to the System Attendant mailbox in the Active Directory directory service. To do so, follow these steps.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 Exchange 2000 Server, or both. 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.  Install the Windows 2000 Support Tools from the Windows 2000 Server CD. Open ADSI Edit or the LDP utility, and then locate the Microsoft System Attendant mailbox. To do so, follow these steps:  Expand Configuration, (CN=Configuration,DC= ,DC= ), expand Services, expand Microsoft Exchange, and then expand .</li> Expand Administrative Groups, expand, expand Servers, expand  , and then click Microsoft System Attendant.</li></ol> </li> Right-click Microsoft System Attendant, and then click Properties.</li> In the Select a property to view box, click proxyAddresses.</li> In the Values box, verify that the foreign address (GWISE or NOTES) is not present.</li> In the Edit Attribute box, type the address for the System Attendant mailbox. For example, GWISE:ReproExDomain.ExPO.ReproEx2k-SA or NOTES:Microsoft System Attendant/First Administrative Group@Exchange.</li> Click Add, verify that the new address was added to the Values box, and then click OK.</li> Restart the Exchange Calendar Connector, and then verify that Free/Busy information from the foreign mail users is being populated.</li></ol>
