SUMMARY
When you send mail using a Microsoft Exchange client, you receive the
following error message:
Your message did not reach some or all of the intended recipients.
Subject: Subject of the message
Sent: 7/19/96 11:20:50 AM
The following recipient(s) could not be reached:
John Doe on 7/19/96 11:20:52 AM
No transport provider was available for delivery to this recipient.
CAUSE
This error is generally caused by an invalid recipient address. It can
present itself when the address is an unrecognized or unsupported address
type.
For example, using the Personal Address Book (PAB) to address mail.
Typically, when migrating to Microsoft Exchange, users will tend to use a
PAB entry to address mail. In some instances, the address looks like the
friendly name that is also in the GAL, but when getting details of the user
in the PAB, the address will contain that of the old mail system.
RESOLUTION
Delete the address from the PAB and then add the user back into the PAB
from the Global Address Book (GAL).
