Does Mail in Snow Leopard support RPC over http?

Greetings,

RPC is a technology for Outlook Web Access and Exchange, not Mail and Exchange, so the answer would logically be that it is not supported. Entourage for Mac 2008 also does not support that.

That is the 1 million dollar question.
I have the same problem, cannot get email outside the company network, must have a VPN first.

Sorry, but there's no way to do that. OWA is named that way for a reason: it's web access, not mail client access. Mail doesn't support RPC, and neither does Entourage for Mac, so that's strictly a Windoze feature at this time, maybe forever.

Why not just set up the Exchange 2007 server so it works properly ... or am I missing something?

If you point Mail.app to your OWA servers (Exchange 2007) for both internal and external communication, it should work. That's how we have it configured -- we only allow RPC over HTTPS traffic from clients, and Mail.app works fine in that setup.

RPC is strictly for an Outlook/Exchange connection. Apple's Mail program only connects via IMAP, which it sounds like is disabled on your company's mail servers. We are using Exchange 2007, and our OWA servers also have the hub transport role installed on them. We allow SMTP and IMAP connections and by entering the OWA server address (actually autodiscover worked, so I didn't have to enter anything) everything connected fine. Now, there is a different problem where you can't move e-mail messaged to a different folder, but that's already open in another thread.

This reply isn't correct. I've successfully connected to an exchange server using entourage (pre 2008); initial access needs to be configured over a VPN, which is subsequently unnecessary.

I'm not entirely sure whether this was via rpc/http or webdav BUT the calendars populated with information from the exchange servers and scheduling is possible although not with resources etc. as in Outlook. This certainly wouldn't have been possible with IMAP.

Ok, technically Entourage can use WebDAV over http or https ports to connect to Exchange Client Access Servers, but the OP was about Mail, not Entourage.

Wrong, Entourage can connect to an exchange server externally. I haven't found a way to connect with snow leopard as of yet.

Yes, SL mail can provide RPC over HTTP. However you need to have access to owa also.

It works very good on my laptop, without VPN.

In the account, you have an internal and external server - in the advanced you have internal server path and external server path.

The external server in my case is the name of our owa server. E.g

Internal mail server: mail.company.internal
External mail server: webmail.company.com

Under Advanced:

Internal server path: EWS/Exchange.asmx
External server path: EWS/Exchange.asmx

Some need to turn SSL on or off, depends on their Exchange 2007 setup.

Guys,

I need some urgent help here. Got the Macbook Pro 4 days ago and till today, i cant sync to my company exchange server with Apple Mail application. I am a new Mac user and with my current experience, its leaving a bad taste on me. Below are the details on my company's server settings, appreciate for pointers to guide whether to use Exchange IMAP or Exchange 2007, also the settings required for incoming and outgoing mail server. Been trying different combination, but nothing works...
