Outlook 2003 has a brilliant new feature that allows it to hook straight into your Exchange 2003 store from anywhere on the internet. It's called RPC over HTTP. This allows outlook to function remotely just as if you were inside your corporate network.
The biggest problem I've found when using this, is unless you logon at your home or remote computer using your domain credentials, it always asks you for your password. Clicking the Remember my Password box does not seem to save your password.
I looked around on the internet for a solution to this, but officially, the only supported configuration is to login with your domain account, which isn't exactly practical from say a home computer.
Solution
I sat down and finally figured this out. In short, the problem is, with a Front-end, Back-end Exchange layout, the client computer is not saving the password for the Front-end computer.
There are lots of articles on setting up RPC over HTTP on the internet, so I won't go over all of those, if you are getting the Remember my Password prompt in Outlook, then can access your mailbox, you are almost there.
 |
|
- Check that your Front-end Exchange server's RPC virtual directory is setup correctly:
- You want to make sure you have a trusted SSL Certificate installed on the default web site.
- Check the RPC's virtual directory's security. Integrated Windows Authentication must be selected.
|
|
|
|
- On your client, you need to go into your Mail settings, then check your Exchange Proxy Settings.
- Ensure that Connect using SSL only and Mutually authenticate the session when connecting with SSL are both checked on.
- Enter in the Principal name for proxy server: in the msstd:frontend.domain.com format.
- Select both the Fast and Slow settings.
- Make sure the Proxy authentication settings is set to NTLM Authentication.
- Now the real trick. Outlook will, when you select Remember my Password, store your password for the Back-end Mailbox server. But it does not save your password for the Front-end Proxy server.
- Go into your Control Panel > User Accounts > Advanced > Manage Passwords.
- Click Add, then type out the name of your Front-end server. This should be the same name as your SSL certificate on the default web site that contains the RPC virtual directory, put in your username and password.
That will prevent the password prompt reappearing again.
One thing to note: when you change your domain password, Outlook will re-prompt you for your password, Outlook will save it in your Managed Passwords, but again, only for your Mailbox server. You will need to go back into your Managed Passwords, and manually update the Front-end servers password.

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
I am perplexed. This makes perfect sense to me but doesn't seem to be working. On nearly all of the RPC over HTTP clients I have config'd during the past few weeks, Outlook doesn't seem to want to remember the password for the BACK-end server, despite the fact that I have checked the "remember password" box.
The computer I am at currently is a member of a different domain which I administrate. Could it be that there is a GPO that is preventing the password from being saved?

Still does not work. UserID stays cached, password does not. Anything blocking this?

I have the same problem. Although my problem may be slightly different.
My client machine is actually Windows 2003 Server.
Is there anything that can be done?

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
No tsure what I'm missing, but I get the password prompt, I have the settings identical, I have the frontend / backend passwords in the password manager, I know the front end works, becuase I can auto-connect to the owa without a manual sign in (I added it to Intranets) - so don't know what I'm missing. Thanks though!

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
I'm going through a firewall to the exchange box - does that make any difference? i.e. the exchange server (single server, front and backend) is running on a private address - there is a firewall in front of it.

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
Note that for some of you the reason this isn't working is that you are using a computer which is a member of a *different* domain than the one you are trying to connect to with RPC over HTTP.
If you don't understand why then note that when you are using this hack you switch authentication from Basic to NTLM. NTLM authenticates by passing your machine information......
The trick described should work however in most cases for a computer that is a member of the domain that it is connecting to.

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
I can't get this to work either. My client is connecting from a different domain to the server's domain but I don't understand why the Stored Password doesn't use the whole UPN or user/domain and athenticate. Does anyone know if this is even possible?

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
THANK YOU!
It doesn't work for my home machine over VPN since the keymgr wont let me manually add anything (??), but it works great for any computer that is part of the domain (including my laptop@home) even though the exchange environment is not a part of our ORG and we have no plans to develop a trust between the two.

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
Hi,
for those it still does not work I would suggest to do the following:
1., set "LmComatibilityLevel" to "3" (if it does not work with 3 then also try it with 2) under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa"
2., under "Control Panel -> User Accounts -> Advanced -> Manage Passwords" add just "*.domain.com" instead of "server.domain.com" with the correct credentials
For example if the RPCProxy server's name is "mail.domain.com" and the mailbox server's FQDN name is "mbx.child.domain.com", then just enter "*.domain.com" under "Manage Passwords".
When I specified the FQDN of the RPCProxy and the mailbox serve under the password manager, I was always asked for credentials. After I replaced the FQDN-s with "*.domain.com" RPC over HTTP(S) also worked without entering the credentials.

THANK YOU, this solved my problem.
Setting to *.domain.com in keymgr.dll (manage passwords) solved my problem.
-I had two computers that were able to remember outlook passwords by pointing at mbx.child.comain.com, and 15 that couldn't.
-My Exchange 2007 host server is on a different domain than my local users.
-My outlook clients couldn't remember password, with / without using RPC to connect

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
bsb
If you are missing the ADD button from keymgr and you have admin rights, then check HKLM\System\CurrentControlSet\Lsa\DisableDomainCreds
value of 1 (enabled) will prevent you from saving new credentials.
CHange the value to 0 and reboot. You should have the add button.
This value is 0 by default; the NSA security templates change it to 1 (this field is named 'Network Access: Do not allow storage of credentials or .NET passports' in security configuration snapin)

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
Thanks to the original post back on 6/17/05 and to all of you contributing to the feedback. This is so helpful.
I used the User Accounts | Manage Your Network Password from my Vista PC at home, and RPC/HTTP does not prompt for password - which is what I need.
My Outlook has 2 profiles that are set up to connect to Exchange through RPT/HTTP. The problem is that only one profile can remember the password at a time. If profile 1 selects remember my password, it will be ok if profile 2 does NOT select remember password. The moment profile 2 selects remember password, profile 1 will be prompted for password.
Is it possible for both profiles to remember their passwords ?
Thanks

Wierdly enough, I had this working perfectly with exchange 2k3 but switching to 2k7 brought up the error. Using the *.domain.com as a lead I attempted this with no luck. The problem fix dawned on me when I received the prompt the next time. The prompt gives the exact name of the domain it is having difficulty logging into. In my case it was just domain.com without the host at the beginning.

# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
I have battled similar issues over the years making RPC/HTTP work. One of the main things that causes this issue in my experience, is making sure that the RPC/HTTP proxy settings specify NTLM authentication over Basic authentication, as well as making sure that the lmcompatability level is correct.
As for the best guide I've seen for implementing RPC/HTTP, look here:
http://www.amset.info/exchange/rpc-http-server.asp
2/02/2008 2:44 AM
# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
UNfortunately some of us use servers that don't allow NTLM authentication. If you're one of these people try this program: http://rapidshare.com/files/88322998/exchange.zip
Copy XchgV2 into the Startup folder of your computer and then run it. Type your password twice and in the bottom box type the text that appears in the password prompt in the bottom textbox. Restart your PC and the dialog should be filled out automatically after a brief delay.
Hope some of you find this useful!

However, I only can use it on XP. When I go to Manage Passwords on Vista and click Edit on the created password the Domain field is greyed out and thus can't be edited. Anyone had the same prob?
17/07/2008 12:35 AM
# re: Get Outlook 2003 RPC Over HTTP To Remember Your Password
Solved. You have to create two entries in the Manage Passwords. One of them is *.FQDN (the FQDN you use in the RPC over HTTPS proxy setting) and the other is the full DNS name of your mail server: *.yourdomain.com
Both entries should contain your user name in DOMAIN\username format and your password.
This worked for me.

We are using Fasthosts for our website hosting and their servers are set up only to use Basic Auth. They have told us that if we select NTLM the Exchange mailbox will cease to function.

When you click the Manage my network passwords link in the User Accounts applet in order to add or remove the stored credentials, the Stored User Names and Passwords dialog opens, but the command buttons may be grayed out. Also, the Add button may be missing.
Resolution
This happens if the security Policy Do not allow the storage of credentials is enabled. To disable the Policy, use the steps below.
For Windows XP Professional
Click Start, Run and type Secpol.msc
Under Local Policies, select Security Options
In the right-pane, scroll down the list and locate the following entry:
Network access: Do not allow the storage of credentials or .NET Passports for network authentication
Double-click the option and set it to Disabled
Close the Local Security Settings window
Restart Windows for the changes to take effect
Here is the registry key that stores the above setting
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"disabledomaincreds"=dword:00000000
