I've recently moved some email archives to an exchange public folder and I'm trying to add a new Content Source in the SharePoint Search Engine Application. I keep running into errors when attempting to crawl the location. The latest error I'm getting is Access forbidden 403 errors. It generates a warning with Event ID 14 in the event log. I've added read access permissions for the default content access account and I'm still getting that error. I've followed the microsoft KB article on crawling Exchange 2010 public folders by logging into webmail and browsing to the folder I'm trying to crawl and then opening it in a new window and copying and pasting that URL but I'm still getting the errors. Any ideas?
