Show Exchange 2010 calendar via URL without forms

We have OWA set up to use forms authentication - but I ultimately want the ability for Sharepoint to display a public folder calendar (called the oh-so-misleading name "Master Calendar") via a web part.  In attempting to define the URL for this, I realized that we have forms authentication set up with Exchange 2010 - because every time I craft a URL, even in IE, I get the forms authentication screen from OWA.

So I'm trying http://servername/owa/?cmd=contents&module=publicfolders&fpath=Master&20Calendar

Is there a way around this required authentication?

May be this helps: http://community.bamboosolutions.com/blogs/sharepoint_blank/archive/2008/11/20/how-to-avoid-multiple-login-prompts-with-exchange-web-parts.aspx

OR  

You cannot transfer SharePoint credential to exchange server and they have different members provider, so you need to login again for owa web parts.

If you set this for internal users, Please enable windows authentication on your exchange server and try again

I have a need for the same thing.  I have yet to find a way around the authentication as it a link from one resource to another resource (both sites [sharepoint and owa] are housed on seperate servers).  One method that has been recommended is to use NTLM (Kerberos) in IIS and Sharepoint Central Administration site configuration.  I have tried it's configuration using this method but I still get the initial login needed for OWA.

The path your are using does appear to be correct although for usage in a webpart or as displayed on your Sharepoint site I would recommend you add &part=1 to the end of your link.  One of the things I hate though is that you lose the functionality to use your Sharepoint navigation so I would need to open the calendar in a new window.  Havn't tried to tackle that but I'll monitor this question to see if any other ideas are presented.

saige,

So for the sake of just testing this, I enabled Windows authentication; however, any request I make with a ?cmd=anything results in a "bad request", regardless of the browser I use.  My goal is to get it working in IE before trying to throw it into Sharepoint - any thoughts on what I might be missing?  I also tried it with the &part=1 appendage above, same result.  

Thanks!
