I have installed a exchange 2010 CAS and Hub Transport on the same box. Webmail and activesync works fine. However, all of my users on rpc over http can't connect anymore. They works before the upgrade. rpc over http proxy was installed and Outlook anywhere was enabled. The only thing I did to make Outlook anywhere work is to change Outlook 2003 under Exchange Proxy Settings Basic authenication from NTLM. I do want to make Outlook anywhere works the same way as before the upgrade without changing any client settings afraid that there may be seucrity issue too. So, what did I miss? I guss there is a place of authenication I miss. Any suggestion is appreciated.

Make sure you enable "Encrypt data between Microsoft Office Outlook and Microsoft Exchange" in Outlook 2003 Security tab properties for Exchange account.

Hi,

Also ensure the NTLM authentication was configured on the Outlook Anywhere in EMC.

Thanks
