[THIN] Re: OT: Exchange thru internet

Not that I don't understand your advantages compared to POP or IMAP...
 
But given the context of your reply (to Ryan, and his suggestion of publishing 
a Citrix session, running Outlook) - they don't really apply when you consider 
Ryan's suggestion.
 
True, you have the comparison with MAPI over HTTP compared with ICA - but ICA 
should be completely acceptable - bearing in mind it's roots are in suitability 
for low bandwidth - and as far as screen refreshes go, ICA (compared with other 
protocols) excels at partial screen refreshes (given outlook as the 
application).

        MAPI over HTTP with E2K3 and Office 2003 would most likely be a lot 
LESS bandwidth intensive than even a published Citrix session.  You're simply 
sending XML queriers (from what I understand) back and forth as necessary.  No 
screen refreshes required.
        

        I'll also tell you why you want full "exchange thru the internet":
         
        Global Address List (viewing, not just LDAP queriers)
        Server side Public Folders
        Server side Calendars
        Server side Contacts
         
        Just to name a few things that you don't have the ability to use with 
POP or IMAP.  Only available through a published Outlook for Citrix, or MAPI 
over HTTP (new feature).

                I would simply publish the application through Citrix. That way 
you get everything, and on a decent connection a lot less speed degredation.

                 

                What is the reason you want "Exchange over the Internet", 
anyway? I mean, you can set up POP/SMTP with ports 110/25 open and that will be 
fine. But Exchange featured mail is going to be a drag for you to support, in 
my opinion.

                not that this is relevant to Citrix, but Exchange 2003 with 
Outlook 11 (2003) offers MAPI over HTTP.  I'm going to do some testing with it 
tomorrow in fact.  Need to find out if you can SSL encrypt it and if so, how.

                                        yeah i changed the DS and IS ports to 
5000 and 5001 respectively and had all this working using RPC on the 135 
working.  but had to close 135 when blaster came out.  if you find a way to 
change the 135 to somethign else, i'd really like to. i have many users wanting 
the outlook over the internet to work again.

                                        You can change the endpoint itself (the 
link I sent describes that process). The endpoint mapper is a different ball of 
wax. If you did actually do that, then I am absolutely all ears, since this is 
a perennially recurring topic on several security mailing lists I am on, and 
the general consensus has always been: don't allow exchange access direct from 
the internet because of all the nasties out there.

                                         

                                        Anyways, let me know what you find.

                                        If I recall correctly we did change the 
RPC endpoint for it.  I will have to double check my notes though (I could be 
wrong)

                                        Nope. You can change the ports exchange 
uses, but not the RPC endpoint mapper port on 135.

                                         

                                        
http://support.microsoft.com/default.aspx?scid=kb;en-us;155831 details how to 
change the ports exchange uses, but there is no way to change the RPC endpoint 
mapper service port number. Keep in mind that the client still has to identify 
which ports the exchange service is listening on, and that requires a service 
which uses a port that the client knows about ahead of time, in this case, RPC 
on 135.

                                        Actualy you change change the port to a 
static port(by default it will dynamically assign the port once it gets 
connected) even the TCP 135 port.  There are a couple of MS KB's on it (sorry I 
dont have the numbers)  I ended up calling ms and I had it set up in about 20 
minutes

                                        To use the full exchange server client, 
you must open up the RPC endpoint mapper port (135). You can set which port 
exchange actually ends up using, but 135 is used to initiate the process 
whereby the client learns that port number.

                                        I want to be able to hit my exchange 
thru the internet but to do it it says that the RPC port 135 has to be opened.  
Well I don't want to do that for obvious reasons.  Is there a way to change 
which port the RPC uses for exchange?
