Retire Public Folders

infinidem asked
Last Modified: 2012-05-05
I have just completed a project of installing several new Exchange 2007 servers to replace an existing Exchange 2003 server.  All the mailboxes have moved and mail flow into and out of the organization is running smoothly.  The last step before I retire the Exchange 2003 server for good is to do "something" with the public folders.  Going forward my organization doesn't need them, and I don't want to maintain them.  I have copied all the information into a PST file in case somebody wants something so I can just go ahead and delete, however the default public folder store for both mailbox stores is still set to the old server.  Since I have not created a new public folder store and I don't want to create one how do I set the public folder store to nothing?  Is it even possible?

What does it say when you try to "unmount" the old folders?

All the clients have been upgraded to Exchange 2007, although I now have a couple of users using Entourage 2008.  I will look into replicated just the system folder and deleting the remaining folders.


If I dismount the store all the clinets pop up with authentication requests to the legacy server every 2 minutes.  Regardless of the credentials supllied the pop up still continues.  In the settings for the mailbox store in 2007 there is a property field for default public folder store.  This is set to the legacy 2003 server.  Since I have not replicated/created any new public folders I can't point this setting to anywhere else or remove the setting.

Do you mean "All the clients have been upgraded to Outlook 2007"? It isn't the version of Exchange, but the version of Outlook they are running which makes all the difference.

In any event, I'm afraid I'm still pretty sure the answer to this is that you can't do this. If you've had a legacy Exchange organization already in place, then Exchange 2007 being installed into that will automatically use the Public Folder database for its System Folders.



Yes all clients are running Outlook 2007.

What I have done is created a new public folder store and directed the default Public folder property for the mailbox store to that database.
