have an Exchange 5.5 SP3 server servicing 60 Outlook 2000 clients. About half the clients keep getting the following error when sending email to reciepients outside the company:

No transport provider was available for delivery to this recipient


Everyone here is using Outlook 2000. We are using Exchange 5.5 for internal
emails which work fine. If I remove the exchange service off the client I
can then send emails outside from those users that were having the problem.

Now it doesn't happen to everyone and we can all receive emails from outside
the company. I have checked the settings on the users that are having
problems and they are all correct.

I tried moving the exchange services in the delivery tab to the top of the list and that did not work either.

Any help is greatly appreciated

I did check everything that article suggested.  Right now none of those reasons appear to be why I can't get emails to go out.

Are the clients connected or working offline? Have you checked the application event logs on the Exchange server? How much disk space do you have on the server?

Check the order of the services.  In Outlook, Tools-Services-Delivery tab.  Put Exchange Server on top.

Your last article looks like its the reason I am having this problem now.  If I am followiong the article right I should not be using the exchange and internet e-mail services at the same time?

All the clients are connected.  I get no errors in the application logs for Exchange server either.
There is 30g of disk space still left on the server.

Will my email signature work in Office 365?

You've built an email signature using raw HTML code in Office 365, but you can't review how it looks with Transport Rules. So you have to test it over and over again before it can be used. Isn't this a bit of a waste of your time? Wouldn't a WYSIWYG editor make it a lot easier?

Putting exchange server at the top of the list didn't work.  I'm inclined to think this setup was not supposed to work from the begining

the link I posted for KB 245446 ... basically Microsoft states they don't support the configuration and recommend configuring separate profiles ...

SYMPTOMS
When you use a simple Messaging Application Programming Interface (MAPI) profile, you may receive the following error message:

No transport provider was available
CAUSE
Your profile contains both of the following services:
An internet e-mail service such as Simple Mail Transport Protocol (SMTP) or Post Office Protocol 3 (POP3)
-And-

Microsoft Exchange Server service
This behavior is due to the way that MAPI handles SMTP address resolution. While this configuration may appear to work, the resolution order, and therefore the ability to resolve SMTP addresses correctly, may not work. This behavior becomes more noticeable in complex organizations. This configuration also causes issues when you connect to a computer that is running Microsoft Exchange Server.

Microsoft does not support this configuration.
WORKAROUND
To work around this behavior, create two different profiles: one for the Internet mail service and one for the Exchange Server service. For additional informationabout how to set up Outlook profiles and how to configure Outlook to prompt you for a profile, click the article number below to view the article in the Microsoft Knowledge Base:
