1. Can i use the OWA VD setting shown aboveon SiteA and SiteB. Yes You can. 2. Can I use mail1.domain.com as primary url to access active mailbox on SiteA and SiteB? (mail1 NAT with ISP1 on SiteA) You can Use by Setting Http Redirect using IIS. 3. If SiteA is down (power outage) Can I use mail2.domain.com as alternate url to access active mailbox on SiteB? Yes . You can Refer this Link- Last Pane http://technet.microsoft.com/en-us/library/dd979799.aspx Outlook Web App Manual redirection. In this scenario, the client namespace is changing from http://mailred.contoso.com to http://mailpdx.contoso.com. After the user enters logon credentials, the user is redirected to CAS2 in the Portland site through a manual redirection page explaining that the wrong URL was used and that the correct URL is https://mailpdx.contoso.com/owa. 4. If connection between SiteA and SiteB. Can SiteA users use mail1.domain.com and SiteB users use mail2.domain.com Yes Satheshwaran Manoharan | Exchange 2003/2007/2010 | Blog:http://www.careexchange.in

Hi Satheshwaran, Thanks Little confusion...Might be I am repeating my queries. Is this happening because we have configured "Cross-Site Silent Redirection" behavior as Selient mode? Ok As per my understanding 1. Internet link is down to SiteA, WAN link is UP between SiteA and SiteB, Internet link is UP to SiteB In this case If UserA having his mailbox on MBX1, UserA will access mailbox via https://mail2.domain.com? Will this solution work? Or we can have some other bet option to configure OWA virtual directory. Thanks in advance NKumar
