Dear Robert,

Thank you for your post.

Based on my research, this problem is most likely caused by the following
two factors:

1.      The Transmission Control Protocol/Internet Protocol (TCP/IP) stack
is initialized incorrectly.

2.      The following registry key is not installed:


If this is the issue, please save the attached ClientProtocol.re_ file to
the hard disk, rename it to ClientProtocol.reg and double-click it to
import it into the Registry.

To recreate the TCP/IP stack, please try the method in the following
Knowledge Base (KB) articles:

Note: It also apply to Outlook 2002

Create a new profile
If the problem remains, it may be due to a corrupted profile. Let's try to
add a new profile in Outlook 2002. When starting Outlook using this new
profile, all folders will be empty. We will import the original data from
the old .pst file later.

1.      Close all the programs and click Start --> Control Panel.

2.      Click "Switch to Classic View" if the current view is organized by

3.      Double-click the Mail icon and click "Show Profiles ?.

4.      Click Add? type a specific name for this new profile and click OK.

5.      Follow the wizard to configure the Exchange Server e-mail account
in this profile and click Finish.

6.      Go back to the Mail dialog box, click to select "Prompt for a
profile to be used" and click OK.

7.      Start Outlook and prompt to choose the newly created profile. Does
the problem cease?

Please let me know if this addresses your concern, or if you would like
further assistance. I am looking forward to your reply.

Best regards,

thanks that helped
i had to reinstall the TCP/IP stack to get it to work
again, i tried just reinstalling the regkeys but it
complained about security permissions. Seems to have
happened when i installed the outlook2003 beta and then
uninstalled it and reinstalled my outlookXP version.. also
had a problem with the import/export menu choice having
disappeared but i was able to go into the customize menu
and drag it back into my menubar... (a little tricky for
most beginners i would believe)

1. Outlook XP / Outlook 2003 problems...with Exchange 2003


I have the same problem in both applications (outlook XP/2003 beta).
I have two E-mail accounts.

1. is an exchange account (current set as default)
2. a private email account

when I send internal mails (in the office) outlook use the exchange
server...as I set (that is OK!).

;) )
Outlook use also the exchange server to send the email and I get an error

The only possibility to send external mails is for me to set the email
account by hand for every
outgoing mail.

The proble doesn't exist with outlook 2000.
Outlook 2000 automatically use the second email account when it see that the
mail must
be send to an extrenal account.

How can I set Outlook XP / Outlook 2003 beta to do the same as Outlook 2000?
