New Feature in Exchange 2013 Outlook Anywhere

Inorder to achieve the HTTP connection for internal outlook client and HTTPS connections for the outlook client connection over the internet .Then we need to have follow the below rule.

  • Separate hostname for the internalhostname and externalhost should be different
  • The Internalhostname should not be published in the internet ISP DNS
  • The InternalClientsRequireSsl should be set as false and ExternalClientsRequireSsl should be set as true.

Powershell Command

Get-OutlookAnywhere | Set-OutlookAnywhere -InternalHostname “Outlook.mail.com” -InternalClientsRequireSsl $false -ExternalHostname “webmail.mail.com” -ExternalClientsRequireSsl $true

How it works ….

By default always the first HTTP part taken by the outlook to get the details of the url if it fails it goes to the next HTTP part of XML file. In the XML file under the protocol of EXHTTP you can able to view the SSL is off and internalhostname as Outlook.mail.com for the first part HTTP protocol used to connect the internal outlook client. If it fails then it moves to the next part of HTTP part to get connected for the internal outlook client

      <Protocol>

        <Type>EXHTTP</Type>

        <Server>Outlook.mail.com</Server>

        <SSL>Off</SSL>

        <AuthPackage>Ntlm</AuthPackage>

In the XML file under the protocol of EXHTTP you can able to view the SSL is off and externalhostname as webmail.mail.com. Since the first name is unable to resolve fqdn over the internet hence it gets connected to second part of the EXHTTP part. Hence it move to SSL connection

      <Protocol>

        <Type>EXHTTP</Type>

        <Server>webmail.mail.com</Server>

        <SSL>On</SSL>

        <AuthPackage>Ntlm</AuthPackage>

In Exchange server 2013 public folder will be get connected by using the below piece of XML file

      <PublicFolderInformation>

        <SmtpAddress>PFHierarchy@mail.com</SmtpAddress>

      </PublicFolderInformation>

 Note: On performing the above change in co-existence mode of Exchange 2007/2010 with Exchange 2013 there will no impact for the legacy exchange user mailbox. Since it connect using RPC/TCP for MAPI connectivity
