Check the replication interval on the public folder. How many public folder stores do you have? Typically there is one on each mail server and you have to go into the Exchange System Manager and tell each folder to replicate. Each mail server’s mail stores default to the public folder store located on that mail server and if the public folders created on a different mail server are not replicating to other mail servers the other users won’t see the changes. Since you just created this folder you may have forgotten to tell it to replicate to all the other public folder stores. You can use the PFDAVAdmin tool to perform a bulk operation to get all publc folders to replicate to all of your mail servers’ public folder stores. Once it is replicating if you want all users to see changes immediately you can change the replication interval to always run. – This is all pertaining to Exchange 2003 which when I read back over your question you do not mention which Exchange version you are using. That makes a big difference! In Exchange 2007 a public folder store is NOT created by default on mail servers. We have a server dedicated just to public folders in our Exchange 2007 setup. So if you are not using Exchange 2003, please provide the details of what Exchange version you are using. Thanks!
