Exchange 2007 SP1, Public Folders HTTP/1.1 501 Not Implemented, GFI MailEssentials

When accessing https://servername/public on our Exchange 2007 server, we got error:

HTTP/1.1 501 Not Implemented

When logging in to OWA (https://servername/owa), we can access the public folder (menu bottom-left). From the Outlook Client we also access the Public Folders.

This error needs to be solved, so when can activate Public FolderScanning by GFI MailEssentials. Now this fails, we can't connect throug WebDAV

Any ideas?

I would imagine it is because the /public/ URL doesn't exist with Exchange 2007.

I would imagine the setup guide for GFI will guide you as to how to do this (Using WebDAV it may need https://server/webDAV or similar for example), however other EE posts suggest that GFI were late in bringing the PF support in 2007, so check it is actually supported!

Hi djxtreme,

GFI should support x2k7, so it sais in its manual... I believe this is not an GFI issue....
Thanks for your reply,

Do you have the /public virtual directory in Exchange? If not then you will need to create it using the following command:

New-OwaVirtualDirectory -OwaVersion:"Exchange2003or2000" -Name "Public" -WebSite "Default Web Site" -VirtualDirectoryType:PublicFolders

I would delete it and then recreate it then.
You need to use the remove-owavirtualdirectory command, do not delete it through IIS manager.
