Outlook can "Restore missing folders for the default delivery location" if ran with a switch "outlook.exe /resetfolders". This is good for just one or two mailboxes. What can I do if I need to do this trick for multiple Exchange mailboxes? Asking dozens or even hundreds users to log on and execute the command is not an option for me, especially that some users do not even have Outlook installed. Is there any equivalent of this Outlook feature available for the Exchange Server that could be ran globally against all mailboxes? Perhaps PowerShell Cmdlet or third party tool (MfcMAPI, etc.)?
