When users access their mailboxes on a Microsoft Exchange
Server 2007 server, certain Internet Message Access Protocol (IMAP) clients
cannot open the bodies of the e-mail messages. Additionally, users receive the
following error message:
The message from User <E-MAIL
ADRESS> concerning <SUBJECT> has not been downloaded from the server.
You need to take this account online in order to download it.
This issue does not occur on all kinds of IMAP
This problem occurs because of a formatting issue. When this
issue occurs, the IMAP client asks Exchange 2007 to send additional message
body data. Exchange 2007 responds by telling the client that there are no
additional bytes of data to send. However, the IMAP client cannot understand
this response. The IMAP client tries several times again to obtain additional
message body data. Finally, the IMAP client gives up, and then you receive the
error message that is discussed in the "Symptoms" section. This occurs even
though all the message body data is already on the IMAP client.
To resolve this problem, install Update Rollup 3 for Exchange Server 2007. For more information about Update Rollup 3 for Exchange Server 2007, see the following Exchange Help topic:
