If you want to remove this stuff we need to create a Hub Transport Rule:
Open Microsoft Exchange Console
Navigate to:
Microsoft Exchange \ Organization Configuration \ Hub Transport \ Transport Rules

Right Click and select New Transport Rule and name it “Remove headers” click Next,

chose From users inside or outside the organization and select Inside click Next,chose Remove header and as message header just write: Received twice click Next…

You are done… Headers will not be sent any more to users outside the organization…

Saso has an explanation for this phenomenon

I currently use:

As you should decide to use or not to use blocklist providers on your mail servers I am adding interesting article from august 2009 to better understand how this providers work: http://www.allspammedup.com/2009/08/understanding-blocklist-providers/

I wish you luck in fighting spam!

EHLO team r0x! http://msexchangeteam.com/

But nowhere I have encountered the problem describing this error code in combination with Windows Server 2008 and Exchange 2007 SP1 with rollup 5.

Well… As I figured out it apparently does not work – if you want OAB to be distributed by Web-based distribution…

You get this error in your Outlook 2007 SP1 clients (on Windows XP and on Windows Vista)

As I can see there is somekind of permission problem becoues OAB virtual directory points to:

C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB

This directory has NO NTFS permissions for Auhtenticated users… but in IIS there is on this folder a parameter: Pass-through authentication - but as I know it can not work becouse your credentials are not covered in NTFS permissions of that folder.

But it does not work even if you give NTFS permissions to authenticated users… (you are still prompted for username and password in Outlook…)

Maybe I am missing something but weekend is almost over and my users need to use Exchange and RPC over HTTP(s) feature in their Outlooks tomorow… What I did is that I disabled Web-based distribution of Offline address book and I left only Public folder distribution. It took a couple of minutes for autodiscover.xml to update and Outlooks to get new parameters about Offline address book distribution.

Everything works correctly now…

Comments / suggestions appriaciated…

PS.
Hey all you Exchangegurus!
I think you will find this link useful: https://www.testexchangeconnectivity.com/

You need to do it this way:

1. Uncheck Internet protocol version 6 (TCP/IPv6) in your network card properties

2. Delete localhost value for ipv6 in file called HOSTS in C:\Windows\System32\drivers\etc

::1             localhost

or comment it by using # at the start of line

3. Create/add a 32 bit DWORD with name DisabledComponents and value 0xFFFFFFFF to:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters

My setup was Windows server 2008 standard as Hyper-V platform, inside Windows server 2008 standard with Active directory in functional level 2008 – everything updated and clean.

When I changed this three parameters exchange setup completed sucessfuly and now my testing Exchange 2007 is working! Wiiiii!!!

2. step
Import certificate request using web access to your Certification authority - logon as administrator! (WEB SERVER!!!)

3. step
Export certificate to a location on the disk… c:\certnew.crt

4. step
Import-ExchangeCertificate -path c:\certnew.cer

5. step
Enable-ExchangeCertificate -thumbprint 5ACC9A5D90E2CFDBAD6E25CD02362B8954506810 -Services “IIS,POP,SMTP,IMAP”

To remove old certificates:
