The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the msExchFolderAffinityCustom attribute contains any Exchange server names. If the Exchange Server Analyzer finds that the msExchFolderAffinityCustom attribute lists server names, the Exchange Server Analyzer displays a non-default configuration message.

By default, Exchange Server 2003 uses routing groups to determine public folder referrals.

The default for Exchange Server 2007 is to use Active Directory directory service inter-site costs to determine routing for public folder referrals.

If the msExchFolderAffinityCustom attribute lists server names, custom referrals have been configured on the Exchange server. The msExchFolderAffinityCustom attribute is a per-server attribute.

As a general best practice, it is recommended that you use the default behavior for public folder referrals. However, you may have to create a custom referral list. The non-default configuration message is an informational message. No action is required.

To revert to the default configuration in Exchange Server 2003

  1. Open Exchange System Manager.

  2. Locate the server object where custom public folder referrals are configured. The Exchange server name where custom public folder referrals are configured is specified in the Exchange Server Analyzer message.

  3. Right-click Server_Name, and then click Properties.

  4. On the Public Folder Referrals tab, select Use Routing Groups in the Public Folder referral options drop-down box.

  5. Click Apply, and then click OK.

To revert to the default configuration in Exchange Server 2007

  1. The following code is an example of the Exchange Management Shell Set-PublicFolderDatabase command that disables the use of the PublicFolderRefferalServerList for the 'MyServer\First Storage Group\Public Folder Database' public folder database.

Copy Code 
Set-PublicFolderDatabase -Identity "MyServer\First Storage Group\Public Folder Database" -UseCustomReferralServerList $false

The UseCustomReferralServerList parameter specifies whether to use the server costs specified by the PublicFolderReferralServerList parameter. If set to $true, the server uses the PublicFolderReferralServerList parameter costs to make public folder referrals. If set to $false, the server uses Active Directory inter-site costs to make public folder referrals.

Note:
Setting this parameter to $false also clears the PublicFolderReferralServerList parameter.
