    When I wrote ExFolders, I thought the non-canonical Exchange ACL problems were permanently behind us in Exchange 2010. For this reason, ExFolders did not include any functionality to deal with non-canonical ACLs. It turns out I was overly optimistic. In the last few weeks I’ve seen a couple...

  • Blog Post: Public Folder Admin Permissions Versus Client Permissions

    Most Exchange administrators have noticed at one time or another that there are folders they can see and access through admin tools such as Exchange System Manager or PFDAVAdmin, but they can’t see or access those same folders through Outlook or OWA.

  • Blog Post: Fixing Mail Enabled Public Folders per KB 977921

    I admit it. I have gotten lazy about posting my new scripts, and haven't posted anything in forever. Today, someone emailed me about the KB 977921 problem, where a public folder has a directory object but is not flagged as mail-enabled. I wrote a script for this a year ago, and never posted it. So, just...
