SYMPTOMS

After you configure a scoped send connector in Microsoft Exchange Server 2007 for a non-SMTP address space, such as FAX, Exchange users can send messages to those kinds of addresses. However, if the users run Microsoft Office Outlook in Exchange Cached mode, the users receive the following Non-Delivery Report (NDR) message:
Your message did not reach some or all of the intended recipients.
Subject: <subject>
Sent: <date, time>
The following recipient(s) could not be reached: <name> <date, time>
None of your e-mail accounts could send to this recipient.
Note
  • You may send messages to non-SMTP one-off addresses, such as [FAX:xxxx]. A one-off address is an address that does not resolve against a recipient object in Active Directory Domain Services (AD DS).
  • By default, all Send connectors that you create can be used by all the Hub Transport servers in the Exchange organization. However, you can limit the scope of any Send connector so that the scoped send connector can be used only by other Hub Transport servers that exist in the same AD DS site.

CAUSE

This problem occurs because Exchange Server 2007 misses an allowed address type for scoped send connectors. When a server that is running Exchange Server 2007 communicates with an Outlook client in cached mode, the Outlook client maintains the allowed list of address types in the registry of the client operating system. The Outlook client will query the allowed list of address types before the Outlook client sends messages for additional processing to a server that is running Exchange Server 2007. The Outlook client immediately returns an NDR message if the address type is not found in the registry.

RESOLUTION

To resolve this problem, install Update Rollup 7 for Exchange Server 2007 Service Pack 1.
