Microsoft Exchange Returns Microsoft Mail as Undeliverable (151028)
The information in this article applies to:
This article was previously published under Q151028 SYMPTOMS
Microsoft Exchange may not be able to deliver Microsoft Mail messages.
When this occurs, other mail clients (such as Microsoft Windows for
Workgroups mail clients) may be able to deliver Microsoft Mail messages
without problems. Microsoft Exchange returns an undeliverable mail message
to the Inbox with the following error message in the message body:
Your message did not reach some or all of the intended recipients.
Subject: <Message subject>
Sent: <Date> <Time>
The following recipient(s) could not be reached:
'<Recipient's Address>' User on <Date> <Time>
Mail could not be delivered due to a problem with the postoffice.
Contact your administrator.
CAUSE
This problem can occur if the Att folder on the post office is missing or
damaged, or if you do not have the correct access rights for the folder.
RESOLUTION
Contact your post office administrator. The post office may need to be
repaired, or you may need to be given full access rights to it.
MORE INFORMATION
Microsoft Exchange supports and uses Rich Text Format (RTF). Messages sent
to other Microsoft Mail recipients have the RTF information encapsulated
in a Winmail.dat attachment. This file is delivered to the Att folder on
the post office.
If the Att folder on the postoffice is missing or damaged, or you do not
have full access rights to the folder, the attachment may not be delivered.
RTF cannot be disabled for the Microsoft Mail information service in
Microsoft Exchange.
Because other MAPI clients (such as Windows for Workgroups, Microsoft Mail
3.x, and Workgroup Add-On for MS-DOS clients) do not support RTF, no
attachment is generated automatically. Therefore, if the Att folder is
missing, messages that do not contain actual user-enclosed file
attachments can be delivered successfully.
