I just restart our exchange 2003 server. It is published by TMG. Users can’t access owa externally. The web require password indefinitely. But user won’t see the mailbo page.

So you are getting password prompt when accessing the OWA externally! But you see the login page, right?Gulab | MCITP: Exchange 2010-2007 | Lync Server 2010 | Windows Server 2008 | Skype: Exchange.Ranger | Blog: www.ExchangeRanger.Blogspot.com

In IIS checked the EXCHWEB virtual directory , img folder and tried to browse and gif file and we get error :access denided - Checked the authentication on the exchweb and it was anonymous, removed anonymous and enabled (basic and windows integrated)

Hi, What are the differences between the internal and external publishing? Check tmg, iis settings etc. Jonas Andersson | Microsoft Community Contributor Award 2011 | MCITP: EMA 2007/2010 | Blog: http://www.testlabs.se/blog | Follow me on twitter: jonand82
