When you are migrating users from Exchange 2003 to Exchange 2007 and 2010, users that uses Outlook 2003 stop seeing Free/Busy on the users after you turn off or remove Exchange 2003. This has happened to me on two occasions now and you also see the following Event ID:
Event ID : 8207
Category : General
Source : MSExchangeFBPublish
Type : Error
Message : Error updating public folder with free/busy information on virtual machine <Exchange2007ServerName> . The error number is 0x80004005
To resolve the situation do the following:
- Open the Exchange Management Shell
- Run the following command
- get-publicfolder -Identity “\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY” -Recurse | fl name,Replicas
- Notice that at least one of the SCHEDUE+ FREE BUSY folders is missing an Exchange 2010 or Exchange 2007 server listed as a replica. For example, the output may appear as follows:
- Name : EX:/o=contoso/ou=First Administrative Group Replicas : {}
- Run the following to add the Exchange 2007 server as replica for the folder
- Set-publicfolder –identity “\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=<netbios domain name>/ou=First Administrative Group” –Replicas “<exchange server>\Second Storage Group\Public Folder Database”
- Verify that the Exchange 2007 server is added as replica
Note All users whose free/busy data is not populated must accept or decline a meeting request to populate the free/busy data.
