I've successfully configured the Exchage to host multiple domain and the user can access their email over OWA. We have two two companies whom I want to give access via outlook using the VPN. Do do login to their AD, is there a way I can do it?

They don’t have to log on to the Domain. Their workstation can be part of a workgroup or different Domain. Configure VPN or RPCOverHTTP/Outlook anywhere etc etc. When you open the outlook, it will prompt you for a user name and password. Use domain/username format.

where do i need to configure the RPCOverHTTP/Outlook anywhere

where do i need to configure the RPCOverHTTP/Outlook anywhere You have to configure Outlook Anyweher (OAW) on CAS server. Its prerequisite is Windows RPC/HTTP Proxy component, so first insall it over CAS Server and then configure OAW. Here is a very good article for this purpose: http://www.exchange-genie.com/2008/02/configuring-outlook-anywhere-for-exchange-2007-sp1/ OAW enables your outlook clients to access the exchange server over internet, without using the VPN connection.

Look at these articles: http://technet.microsoft.com/en-us/library/bb123513.aspx http://msexchangeteam.com/archive/2007/11/08/447484.aspx Also, here is a good remote connectivity testing tool: https://www.testexchangeconnectivity.com/ Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX http://blogs.sivarajan.com/ http://publications.sivarajan.com/ This posting is provided "AS IS" with no warranties, and confers no rights.

is it goign to affect anythign on the server? will it restart the services? I've two non-clustered CAS but Mailboxes are Clusterted Active-Passive, would they be affected with this change?

Hi, It doesnt restart the services nor demand system restart. It just takes 15 mins time when u enable OWA, an event is logged into Event viewer, and it wont affect any outlook mailbox connections. Regards,Laeeq Qazi|Team Lead(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com

what ports do i need to allow on my firewall?

i got the ports 6001,6002 AND 6004 NOW it is runing [PS] C:\Users\administrator.EAFG\Desktop>Get-OutlookAnywhere ServerName : EAI-MAILOWA-02 SSLOffloading : False ExternalHostname : mail2.ediblearrangements.com ClientAuthenticationMethod : Basic IISAuthenticationMethods : {Basic} MetabasePath : IIS://EAI-MAILOWA-02.eafg.local/W3SVC/1/ROOT/Rpc Path : C:\Windows\System32\RpcProxy Server : EAI-MAILOWA-02 AdminDisplayName : ExchangeVersion : 0.1 (8.0.535.0) Name : Rpc (Default Web Site) DistinguishedName : CN=Rpc (Default Web Site),CN=HTTP,CN=Protocols,CN= EAI-MAILOWA-02,CN=Servers,CN=Exchange Administrati ve Group (FYDIBOHF23SPDLT),CN=Administrative Group s,CN=EAFG,CN=Microsoft Exchange,CN=Services,CN=Con figuration,DC=eafg,DC=local Identity : EAI-MAILOWA-02\Rpc (Default Web Site) Guid : 0d122ec5-04a1-401f-a485-2d5ebd9e2efb ObjectCategory : eafg.local/Configuration/Schema/ms-Exch-Rpc-Http-V irtual-Directory ObjectClass : {top, msExchVirtualDirectory, msExchRpcHttpVirtual Directory} WhenChanged : 5/24/2010 11:42:25 AM WhenCreated : 5/24/2010 11:42:25 AM OriginatingServer : eai-dc-02.eafg.local IsValid : True I'm not sure if my outlook is using RPC or MAPI?

when I run the netstat -ns on the CAS 02 server it doesn't show if it is listening on the 6001,6002 and 6004 ports.
