Cannot recover deleted public folder

A user deleted a public folder and needs the folder restored.  I followed the steps in MS KB924044 but it keeps failing.  No matter what, I cannot recover the deleted public folder with PFDAVadmin.  After I select 'Show deleted subfolders' it shows up in the list of public folders in red.  I then select the folder, right-click and select recover.  After a couple seconds I receive the message:
"An unexpected error occured. Exception: time out"

Also, I  tried to recover delete items with OWA, Outlook and MFCMAP.
I get message "You don't have permission"

This is Exchange 2003 Server (Ver 6.5 build 7638.2 SP2)
The account I use should have full permissions on this server.

Have one of the users who had ownership rights log in and try to recover.

Open outlook.  Go to the folder above, and in tools, try the recover deleted items.

There was a OWA hack that could also be used for recovering deleted folders ... something like this.  First is for a user and second for public folders.

http://servername/exchange/username/Deleted%20Items/?cmd=showdeleted&btnClose=1
and
http://servername/public/toplevel/subfolder/?cmd=showdeleted&btnClose=1

You may also want to try the "DumpsterAlwaysOn" registry key which allows you to use the "recover deleted items" from any folder.

After a hard delete, you may still be able to recover mail items from an Exchange mailbox -- it depends on what the Exchange server's delete retention time is set for.

Typically only enabled for the Deleted Items folder. Items hard-deleted from Sent Items, Drafts, Outbox or Inbox are usually gone for keeps.

You need to edit the client registry accessing the Exchange server through Outlook:

Open the registry.
Navigate to HKEY_LOCAL_MACHINESOFTWARE\Microsoft\Exchange\Client\Options.
Add a DWORD value named DumpsterAlwaysOn and set it to 1.
Restart Microsoft Outlook to make the change take effect.

The key is ... have the user try to recover.  It has to be somebody who had permissions before.

My apologies.  I reread your problem and saw that you tried the OWA bit already.

For exchange, are you using the ShowSecurityPage to show permissions?

Very useful

I tend to find that OWA is the best tool to use for this. Login as the user who deleted the public folder. You have to manipulate the URL.

If the folder that was deleted was a sub folder of a main folder called Contacts, then the URL would be http://server/public/contacts/?cmd=showdeleted

You are browsing to the folder immediately above the one that was deleted.

These can be almost impossible to recover if the acct used to recover did not have Owner permissions to the Parent folder and all the way down to the last subfolder before deletion occurred.  Our policy on PF's is to set a Group with all the administrators as members and then assign Owner permissions to the group on ALL PF's. If the users decide to remove the group or reduce it's perms, they do so at their own risk as this reduces our success rate in recovery.

Now, having said that, you might try this... If there was a Group assigned ownership of the PF & it's children prior to the deletion, try adding your acct to that group. Also make sure your acct has Owner perms to the Parent folder. Then you might have better success at recovery.

If you have backups, you will have to restore them to an offline server.  Public folders cant be restored to a production machine.  As soon as you restore to a production machine, they may get deleted again becuase the "delete" action is in the log files.

Were there any nested folders in the folder deleted?

What is your deleted item retention time on the public folders?

Did the DumpsterAlwaysOn registry key help at all for restoring with the Outlook client?
