When you configure redirection from a top-level directory, a web.config file may be created under <drive>\Program Files\Microsoft\Exchange Server\<version>\ClientAccess\oab. If this has happened and you later remove redirection, Outlook may freeze when users click Send and Receive. To avoid this happening after you remove redirection, delete the web.config file from <drive>\Program Files\Microsoft\Exchange Server\<version>\ClientAccess\oab.
