Some history on our setup: This was a Windows 2000 AD with a Exchange 2003 Server. We decided to migrate to exchange 2007 and installed 2 Server 2003 DCs. The Outlook 03 clients don't seem to be getting everyone's calender or updated contact lists. This is the error I'm seeing on the exchange server and believe it is related to the 03 client issues. Event Type: Error Event Source: MSExchangeFBPublish Event Category: General Event ID: 8207 Date: 6/19/2009 Time: 8:29:21 AM User: N/A Computer: EXCHANGE2K7 Description: Error updating public folder with free/busy information on virtual machine EXCHANGE2K7. The error number is 0x8004010f. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I've run this command in the EMS: Get-PublicFolder -Identity "\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY" -Recurse |Select Name, ParentPath, Replicas |FL Here is the output: Name : SCHEDULE+ FREE BUSY ParentPath : \NON_IPM_SUBTREE Replicas : {} Name : EX:/o=EMCParadigm/ou=Exchange Administrative Group (FYDIBOHF23SPDLT) ParentPath : \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY Replicas : {PublicFolders} I've read through tons of blogs, forums, and articles about this error and none of them have been able to solve the issue. What can I do to diagnose this problem?

In case anyone else has this problem, I found this solution on another form: ased on your description, I think that you have two options currently: 1. As you do not use public folder at all, I think you can simply ignore the issue. I would like to explain that for Exchange 2007 and Outlook 2007, they obtain free/busy information by using Availability service instead of public folder which used by Exchange 2003 and Outlook 2003. The availability service obtains the users free/busy information from his mailbox directly. 2. As you may already know, the Outlook publishes Free/Busy information into public folder based on its LegacyExchangeDN attribute. For example, if the users LegacyExchangeDN attribute is/o=contoso/ou=First Administrative Group/cn=Recipients/cn=testuser, the Free/Busy information for the user is published to the\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX: /o=contoso/ou=First Administrative Groupfolder. For new users whose mailbox are created on Exchange 2007 directly, the Free/Busy information is published into\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=orgname /ou=Exchange Administrative Group (FYDIBOHF23SPDLT)folder. It is because the legacyexchangedn of the users are/o=orgname/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=username. Nevertheless, for users whose mailbox is migrated into Exchange 2007 from Exchange 2003, their legacyexchangedn is /o=orgname/ou=First Administrative Group/cn=Recipients/cn=username. Therefore, the free/busy information for the users should be published into\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX: /o=orgname/ou=First Administrative Groupfolder. From your output, the\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX: /o=orgname/ou=First Administrative Groupfolder does not exists. Therefore, I think the issue mostly occurs because the legacy mailbox which is moved to Exchange 2007 unable to locate the Free/Busy folder to publish the Free/Busy information. I suggest you create a public folder to check whether the issue can be solved. You can refer to following command to create a new public folder: New-Publicfolder -name "EX:/o=ORGName/ou=First Administrative Group" -path "\non_ipm_subtree\schedule+ free busy" Note: If your original Exchange has different Admin Group name, you need to change the command.
