I am running a mixed exchange 2003/2007 environment. There is one 2003 SP2 server running nntp on a Windows 2003 server. The rest of the servers are Exchange 2007 SP2 RU2 on Windows 2008 SP2. For quite some time I have noticed that mail-enabled public folders show as such in the Exchange 2003 system manager and the Exchange 2007 Management Shell. However, the Exchange 2007 Public Folder Management Console incorrectly displays some of the folders as mail-disabled. The affected folders still receive mail but we can't manage them properly from the management console since it doesn't believe they are mail-enabled.Any ideas?Micah

Does the issue happen to newly created public folder? Please compare the replica list between the problematic public folder and the fine one Please also compare the attributes of the public folder object between the problematic ones and the fine ones in the AD Exchange 2007 can still display some mail-enabled public folder correctly, please focus on the comparison between these working ones and the problematic onesJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

Hi,If you find that the public folders are not able see them as mail enabled then try mail disabling and again mail enablingalso you can use the PFDAVAdmin and check the foldersalso check for the Legacy ExchangeDN values and check the proxy addresses of those folders
