I am unable to sync my device now that I moved my mailbox to my new exch 2007 server. I am trying to connect from the Internet thru our exch2003 server. Does anyone know what permissions need to be set on the variouls virtual directories to get this to work? If i come straight into my exch 2007 server from the internet both activesync and outlook anywhere work fine. Thanks!

Hi, You can't connect to an exchange 2007 server using an exchange 2003 server as a front-end server. Leif

My Exch2003 server is not configured as a front-end server. It was the only Exch server in the org. Now that I have added an Exch2k7 server I need to migrate users over and still allow our devices to sync, as well as IMAP and POP3 should also function properly. Are you saying that isn't possible?
