Whitelisting in Exchange 2003

I neede a way to create a whitelist in Exchange 2003. Apparently the support for whitelisting is not very good. Here are some options:

1. Global Accept List

You can add the IP och a “Safe” mail server.


2. Custom Weighting

You can add an XML file containing rules for changeing the SCL value based on SUBJECT or BODY


3. White list Recipients (Note: Not Senders)

You can add certain recipients for whome you will not filter email.

Redirect to /exchange in Exchange 2003

How do I redirect the default web site to /exchange ?

1. Log onto the OWA server

2. Open the IIS Manager

3. Open the properties for the default web site

4. Under the Home Directory Tab, do the following

a) Choose redirection to a url
b) Type /exchange in the text box
c) Check the “directory under this one” radio button

5. Click “apply”, “OK”, and exit the IIS manager.

6. Test the changes by opening a web browser, and connecting to the www root folder.  It should now take you directly to the Exchange Logon screen.

Setup Wizard for Update Rollup 2 for Exchange Server 2007 (KB 935490) ended prematurely because of an error. Your system has not been modified. To install this program at a later time, please run the installation again.


This issue occurs if the %SYSTEMDRIVE%ExchangeSetupLogs folder has been deleted, renamed, or moved after the installation of Exchange 2007.
Note The %SYSTEMDRIVE% variable represents the root directory of the drive on which the operating system is installed. For example, %SYSTEMDRIVE% might represent drive C.


To resolve this issue, follow these steps:

If the ExchangeSetupLogs folder was renamed or moved, restore it to the root folder of the drive on which the operating system is installed.
Note The ExchangeSetupLogs folder may have been removed, and you may be unable to restore it. In this situation, create an empty folder that is named ExchangeSetupLogs in the root folder of the drive on which the operating system is installed.

Reinstall Update Rollup 2 for Exchange 2007.


I simply downloaded Roll-Up Fix 6 and installed it.

Event ID 12014 – Microsoft Exchange couldn't find a certificate

Event ID 12014 may appear in the Application event log of CAS/HUB Transport/Edge server:

         “Microsoft Exchange couldn’t find a certificate that contains the domain name mail.domainname.com
         in the personal store on the local computer. Therefore, it is unable to offer the STARTTLS SMTP
         verb for any connector with a FQDN parameter of mail.domainname.com.
         Verify the connector configuration and the installed certificates to make sure that there is
         a certificate with a domain name for every connector FQDN.”


This means that you are missing a cert for a SMTP connector

Here is the solution:


New-ExchangeCertificate -Domain Name “mail.yourdomain.com”, “computername” -Services “SMTP”

Enable-ExchangeCertificate “thumbprint recieved above” -Services “SMTP”

public name to fix the following error.

Error c103b404

Uncheck “Require secure channel” and “Require 128-bit encryption”
Add local and external hostname to hostfile

    ISA and OWA problem(s)

    I had a customer who was having a problem with a ISA published Exchange 2003 OWA. Phe problem had two symptoms:

    1. When they clicked on an URL in a mail in OWA they where redirected to a login page.

    2. When the create a new message and attach a file they get redirected to a login page.

    Turns out this was tho separate problems:

    URL problem:

    This is a problem with authentication settings in IIS


    Attachment problem:

    This is a problem with the delegation to the backend Server. This is a known bug in ISA 2007. There is a hotfix but you have to call PSS to get it.
