The information in this article applies to:


 * Microsoft Windows 95

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:  Sent:     

The following recipient(s) could not be reached:

'' User on   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.
