= Microsoft Exchange = ''This page should have a lot more information about Exchange. For now it's just a collection of notes.'' Exchange 365 returns an incorrect BODYSTRUCTURE response for single part messages, failing to include the message disposition value in parentheses as required by the IMAP spec. See [http://kenai.com/bugzilla/show_bug.cgi?id=5218 this bug report]. This causes a MessagingException with the message "Unable to load BODYSTRUCTURE". Use the workaround described in the [http://www.oracle.com/technetwork/java/javamail/faq/index.html#imapserverbug JavaMail FAQ]. Exchange 2010 has a bug where it fails to quote the encoding value in a BODYSTRUCTURE response. This causes a MessagingException with the message "Unable to load BODYSTRUCTURE". As of 1/10/2011, a customer reported that Microsoft expects to fix this bug in "Roll Up 3" for Exchange 2010. JavaMail 1.4.4 includes a workaround for this Exchange bug. Exchange 2007 has a bug where it returns "-1" as the size of a multipart/signed body part (at least) in the BODYSTRUCTURE response.. This causes a MessagingException with the message "Unable to load BODYSTRUCTURE". Use the workaround described in the [http://www.oracle.com/technetwork/java/javamail/faq/index.html#imapserverbug JavaMail FAQ]. Exchange 2007 has a bug where it advertises that it supports AUTH=PLAIN, even though [http://technet.microsoft.com/en-us/library/cc540463.aspx this Exchange documentation] claims that it's not supported. This causes JavaMail to choose PLAIN authentication, which will always fail. To work around this Exchange bug, set the session property "mail.imap.auth.plain.disable" to "true". (Change "imap" to "imaps" if you're using the "imaps" protocol.) To access a shared mailbox in Exchange, you need to login using the "alias" name and password for the shared mailbox, which you can get from your Exchange server administrator.
