During Exchange 2010 deployment, you can see that Exchange 2010 Outlook Anywhere not working. One of the best tools for tests and diagnostics is https://www.testexchangeconnectivity.com/ website.

When you run “Outlook Anywhere (RPC over HTTP)” test you can see the error that contains the following message:

“The EXCH provider section is missing from the Autodiscover response”

I’m sure, you already checked all Internal / External URL settings

But, have you checked your Mailbox Database settings and see what do you have configured as RPCClientAccessServer? You can do this by running the following cmdlet:

Get-MailboxDatabase | fl Server, RPCClientAccessServer

If your RPCClientAccessServer is not set or set not exactly as it supposed to be, you can  correct this as illustrated in the following example:

Set-MailboxDatabase -Identity “Mailbox Database 0447493325″ -RpcClientAccessServer outlook.curu.local

Note: In my case outlook.curu.local is a FQDN name of my Network Load balancer
