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). -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Ryan Lambert Sent: Thursday, August 28, 2003 8:16 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Exchange thru internet 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. -Ryan -----Original Message----- From: Evan Mann [mailto:emann@xxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, August 27, 2003 7:58 PM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Re: OT: Exchange thru internet 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. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of John Knightly Sent: Wednesday, August 27, 2003 6:30 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Exchange thru internet outlook over the internet...are you smoking crack? -----Original Message----- From: Jeanne Shotton [mailto:jeanne@xxxxxxxxxxxxxxxxx] Sent: Wednesday, August 27, 2003 3:06 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Exchange thru internet amen -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of M Sent: Wednesday, August 27, 2003 5:04 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Exchange thru internet Dare i mention the words Citrix Secure Gateway ? i did think this was a Citrix forum :¬) ----- Original Message ----- From: Michael <mailto:MBoggan@xxxxxxxxxxx> Boggan To: 'thin@xxxxxxxxxxxxx' <mailto:'thin@xxxxxxxxxxxxx'> Sent: Wednesday, August 27, 2003 10:53 PM Subject: [THIN] Re: OT: Exchange thru internet 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. _________________________________ Michael Boggan Network Engineer/Citrix Admin Virtual Desktop Inc.

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. -----Original Message----- From: Magnus [mailto:magnus@xxxxxxxx] Sent: Wednesday, August 27, 2003 3:29 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Exchange thru internet If I recall correctly we did change the RPC endpoint for it.

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 <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. -----Original Message----- From: Magnus [mailto:magnus@xxxxxxxx] Sent: Wednesday, August 27, 2003 11:02 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Exchange thru internet 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 Magnus -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Henry Sieff Sent: Wednesday, August 27, 2003 11:49 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Re: OT: Exchange thru internet 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. -----Original Message----- From: Michael Boggan [mailto:MBoggan@xxxxxxxxxxx] Sent: Wednesday, August 27, 2003 10:41 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] OT: Exchange thru internet 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? _________________________________ Michael Boggan Network Engineer/Citrix Admin Virtual Desktop Inc.
