We are running exch2003 ent with Win2k3 and recently one of the user deleted public folder email enable folder. I have tried to recover by following means: - Recover deleted Items from Outlook (no avail)- Use Adrestore.exe -r (command was successful but deleted item wasn't visible from Outlook or Exchange pub folder)- Then I have recreated email enable folder by same name but when I try to add email address, message pop-up saying that email address already exists. Now how do I clean-up and able to add back the old email address to the folder?Appreciate your kind help!! Thank you.

In case you will encounter this situation [Users deleted public folder by accidently] again, heres a tool PFDavAdmin which may help to recover deleted public folder at that time 1. Launch tool 2. File menu->connect->set the parameters and OK 3. Right-click Public Folders->Show deleted subfolders, the deleted folders will be showed as red font 4. Right-click those deleted folders->Recover folder, and then the folder will be back to public folder tree
