Question ID: 183248
I've been researching this problem for hours and can't seem to
formulate the right query, so I thought I'd ask some humans:

I want to access my workplace Outlook email from home. The problem is
that I don't know the Exchange Server IP address or host name. I have
set up VPN access and have successfully mapped to my work desktop C:
drive.

My question is: is the Exchange Server address stored anywhere inside
the Outlook files on my workplace desktop, and if so -- where?

Looking forward to any tips,
A.

Thanks, zanthius-ga. One clarification -- I was trying to find the IP
address without having to run Outlook at work. I want to know where
exactly, in the raw Outlook files, is the IP address stored, if
anywhere. But thanks for your help.

Dear nyura6-ga,

Unfortunately, Outlook doesn't happen to store the Exchange server
address in its .pst or .ost files that may be associated with a
particular Outlook instance. However, all is not lost - this
information is stored in the registry, and if you have access to it,
you can find it through there.

Run registry editor ("regedit"), "Connect Network Registry..." to your
work machine, and navigate your way down the tree to:

HKEY_CURRENT_USER
  Software
    Microsoft
      Windows NT
        CurrentVersion
          Windows Messaging Subsystem
            Profiles

(Obligatory Warning: Be very, very careful not to change anything when
using registry editor, as bad things tend to ensue from any change
that isn't exactly right...)

Underneath this key, you will see a list of all the Outlook/MAPI
profiles set up on your machine. If there's only one - which is likely
- that's the one you're looking for; if not, you need to find the one
which your Outlook is set to use. In either case, select it.

And at this point it gets complicated. Outlook profiles aren't
designed to be human-readable, so underneath that key are a large
number of keys designated by lengthy hexadecimal numbers, each of
which contains values designated by, once again, lengthy hexadecimal
numbers. You pretty much need to look through all of them until you
find one of the ones which contains a value resembling:

001e6620      REG_SZ      Microsoft Exchange Server

(the initial number may vary). There are several of these, and most of
them contain the name of the Exchange server (only one doesn't on my
test system here, and that can be identified as it references
emsui.dll in another value).

To find the name, look through the other REG_SZ values in the key - by
eliminating the references to your user name, Outlook, full name,
etcetera you should be able to identify the Exchange server name.
Pinging this from a command prompt should then give you the address.

Another possible method is by examining the Internet message headers
on a message received with the Outlook in question, by using "View",
"Options..." when looking at a message (although if you don't want to
run Outlook, this won't work for you; I list it here as another
possibility just in case, though, or in case you have any messages
stored elsewhere, exported or in .pst files).

What you want to look at is the "Received:" headers:

Received: from some.sending.guys.com ([192.168.10.2]) by
exchangeserver.example.com with Microsoft SMTPSVC(5.0.2195.5329);
	 Thu, 13 Mar 2003 12:03:08 +0000

Find the most recent one, which will mark the reception of the mail by
your Exchange server, and the "by ..." field should tell you the full
name of the server. Again, pinging it will give you the address.

You should be aware, however, that in large Exchange organisations the
server that receives the messages is often not the one that stores
them for Outlook, so this is not as reliable as the remote-registry
method.

celebrate-ga,

thank you very much for the awesome information. I checked both
methods and both worked (our "receive" and "store" Exchange servers
are the same).

I forgot about my question for a while because I now access using a
different method -- XP's Remote Desktop. So I now do run Outlook at
work. From home.

Thanks for the help. Though I wonder if it would be possible to find
this on Google. This was the first time I couldn't ask it the right
question.

Your Outlook server name is stored in outlook.  (Using outlook 2000)
Click on Tools - Services.  You sould see Microsoft Exchange Server on
the list, click on it and select properties.  You should then see your
server name up the top.

To convert this name to an IP address.  In DOS type: ping [name of
server]

e.g. (what came up on my PC)

H:\>ping sbw2xxx

Pinging sbw2xxx.xxxx.com.au [xxx.xxx.4.36] with 32 bytes of data:

Reply from xxx.xxx.4.36: bytes=32 time=32ms TTL=125
Reply from xxx.xxx.4.36: bytes=32 time=16ms TTL=125
Reply from xxx.xxx.4.36: bytes=32 time=16ms TTL=125
Reply from xxx.xxx.4.36: bytes=32 time=16ms TTL=125

Ping statistics for xxx.xxx.4.36:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 16ms, Maximum =  32ms, Average =  20ms

(replaced some numbers with x's for security reasons)

That number 'Reply from .....' is the IP address of your exchange
server.

Hope this helps.
