Accessing Exchange via OWA

    Question

  • I am experimenting with running Exchange 2007 in conjuntion with Exchange 2010. I installed Exchange 2010 into the same domain as my 2007 environment and all seems to be running ok however I cannot access a 2007 existing account by connecting to the 2010 server via OWA. Not sure what the issue is but as soon as I am presented with the OWA authentication, type in the credentials, press enter, I get this message:

    Your request couldn't be completed because no server with the correct security settings was found to handle the request

    I am assuming this is IIS related by can't figure out where to set the security required. I didn't have this issue when I installed Ex2010 into its own domain.

  • Hi,

    You have to go through the proper coexistence steps as Exchange 2010 CAS cannot access OWA for Exchange 2007 users. This will help get started;

    Essentially you need to maintain a legal hostname for Exchange 2003/2007 users. For your Exchange 2010 OWA virtual directories you need to then set this legacy host name to ensure single-sign-on redirect for Exchange 2003/2007 users happens correctly.

    For example of Contoso.com needed their Exchange 2003/2007 usres to log into the 2010 OWA page and then get to their mailboxes it may look like this.

    Set-OwaVirtualDirectory -identity "Servername\owa (Default Web Site)" -Exchange2003URL https://legacy.contoso.com/exchange

    The '2003' in the attribute is correct no matter if that legacy URL is pointing to Exchange 2007 CAS servers or Exchange 2003 Front-End servers.

  • I am also getting this error and have tried setting the virtual directory as stated above. I have 1 new exchange 2010 server with the mailbox, client access and Hub transport installed. I also have 2 other exchange 2007 servers with all 3 roles.

  • I am running Exchange 2003 and am in process of moving to 2010. Everything is up and running just fine. My question is once I have everything moved over to 2010 and am ready to decommision my 2003 server, do I need to do anything to back out the settings that you quoted above. "Set-OwaVirtualDirectory -identity "Servername\owa (Default Web Site)" -Exchange2003URL https://legacy.contoso.com/exchange"

    Does that need to change or be removed? Thanks!
