When you use a simple Messaging Application Programming Interface (MAPI) profile, you may receive the following error message:
No transport provider was available
Your profile contains both of the following services:
To work around this behavior, create two different profiles. One profile is for the Internet mail service, and one profile is for the Exchange Server service.

Another way to work around this behavior is to use Outlook Express for POP3 or SMTP internet e-mail services, and to use Outlook when you connect to a computer that is running Exchange Server.
This information applies to using Microsoft Mail in a profile with Exchange and/or Internet Mail Service. In addition, Microsoft recommends that you have a separate profile for the Microsoft Mail service.
If you install Internet Mail Service (IMS) on a computer that is running Exchange Server, mail is automatically sent using Exchange Server. The SMTP server that you specify as your Internet e-mail account is not used.
The Outlook program, acting as the Exchange client software, sends an NspiResolveNames request to Exchange Server. If you install IMS, Exchange Server attempts to handle the message even if you have not correctly configured it to send Internet e-mail. In such a situation, a non-delivery report (NDR) is received.
There is no client resolution available for this situation other than the use of separate user profiles for Outlook. Configure Exchange to send SMTP mail by installing IMS, or to use another e-mail program to send Internet e-mail.
