Re: Outlook won't connect locally when configured for HTTP

Chace,

Thank you for your interest in helping me solve this problem. My boss, and
the laptop in question, just returned from a vacation so I can try trouble
shooting again.

I think you slightly misunderstood my issue. When the computer is not on
the lan it connects via RPC over HTTPS perfectly. When the computer is on
the lan it tries to make an RPC over HTTPS connection first whether the box
for "On fast networks, connect using HTTP first, then connect using TCP/IP"
is checked or unchecked. I have tried both. When it tries to make the
HTTPS connection it fails because our firewall won't allow an internal
computer to connect to our network by going out to the internet service
provider and back to our network. This means that the connection will not
be successful. Eventually the connection tries are exhausted and it makes a
connection via TCP/IP. It works, but it takes 15 or so minutes to go
through the process. This means that it takes a long time from when he
starts up the laptop until he can actually start working. It was working
perfectly until a couple of months ago. Then it started the process I have
described above.

I have tried deleting the mail profile and that has not had and effect. I
have verified the setup, it all looks correct and it functions perfectly
when not on the lan. I have verified the certificate trust and it works
properly also. I am not able right now to check the
https://company.com/rpc/ page as I have to get the laptop off our network.
I don't think this will be the issue because remote connections have been
working flawlessly. If it could be a problem even though the remote
connection is working please let me know and I will take the laptop to a
remote location and try the connection to https://company.com/rpc/.

Thank you,
Robert

Hi,

Thanks for posting here. I appreciate Russ and Lanwench's input

From your post, I do undersatand when you access exchange via RPC OVER
HTTPS, always trying to conncect. If I have misunderstood your concern,
please feel free to let me know.

Based on my knowledge, in most cases, the RPC over HTTPS issue of the SBS
2003 servers could be caused by the certificate trust. The web server
certificate issued by the SBS CEICW is not trusted by the IE client
natively. When we connect to the SBS server through RPC over HTTPS, since
there is no mechanism to prompt the certificate security alert (as IE
does)
to let the user to confirm the connection, if the certificate is not
trusted by the client computer, the RPC-HTTPS would not be established.

Here, I suggest you refer to the instructions in RWW site and then
reconfigure the remote Outlook client. You may open Internet Explorer,
access https://FQDN/remote and input the credentials. Click the link
'Outlook via Internet'. After doing the steps, will you be able to
establish the RPC-HTTPS connection?

If the problem persists, please help to collect the following information
for further analysis:
1. Please try to access the URL: https://company.com/rpc/ Will you get any
security alert regarding the certificate? After inputting the credentials,
what message do you get from the browser?

2. Use the RPCping utility to dialog the RPC over HTTPS traffic from the
external network. What's the result?

831051 How to Use the RPC Ping Utility to Troubleshoot Connectivity Issues
with
http://support.microsoft.com/?id=831051

Install the RPC ping utility on the client computer and then open a
command
prompt, run the command as the following example:

rpcping -t ncacn_http -s SBSlocalname -o RpcProxy=www.mydomain.com -P
"user,localdomainname,*" -I "user,localdomainname,*" -H 1 -u 10 -a connect
-F 3 -v 3 -E -R none

I appreciate you taking time to perform the tests. If you have any
questions or concerns, please feel free to let me know. I look forward to
your reply!

Have a nice day!



Best Regards,

Chace Zhang (MSFT)
