Is there any way we can grant permission to user's calendar in trusted/trusting domain?

Hi Rkart77, What’s the Exchange version? The answer is no for Exchange pre-2010 version. You can only share free/busy info via the Availability Service (Exchange 2007): http://technet.microsoft.com/en-us/library/bb125182.aspx And IOREPL (Exchange 2003): http://www.microsoft.com/downloads/details.aspx?familyid=e7a951d7-1559-4f8f-b400-488b0c52430e&displaylang=en Exchange 2010 will allow users cross forest to share free/busy info, calendars and contacts via the new federations features in this version. You can also use the these federation features if you have two Exchange 2007 SP2 orgs in which at least one Exchange 2010 Client Access Server has been deployed. Hope this helps. Thanks, Elvis
