We just migrated from Exchange 2003 to 2007, we have a in house software with downloads emails via POP3, and parses them programmatically. This was working fine under Exchange 2003, the messages pulled from POP3 server on the old server came down in plain text, long lines were wrapped only on spaces, and the trailing space was retained. In Exchange 2007, long lines are wrapped hard at 76 characters, which break the parsing program, it can't cope with line breaks in the middle of words, or with out the trailing space before the "=" I have triedall of theMIME encoding settings for POP3, and I also tried resetting the ByteEncoderTypeFor7BitCharsets value to 0, per KB article: 946641. None of these have helped. I need to recreate the behavior under 2003, is there a way to do this? Would one of the other ByteEncoderTypeFor7BitCharsets options (2,5,6,13, 14) work? If so, what other effects will choosing one of those options have on general emails? Below are samples of the email source for two messages, the first is from 2007 and is the unwanted behaviour, the second is from 2003 and is the wanted behaviour. ##################### Bad Message format ############################# From - Fri Sep 05 11:01:37 2008X-Account-Key: account6X-UIDL: 38X-Mozilla-Status: 0001X-Mozilla-Status2: 00000000X-Mozilla-Keys: Received: from exchangeserver byexchangeserver with mapi; Fri, 5 Sep2008 11:01:36 -0700From: blankedTo: blankedCC: blankedDate: Fri, 5 Sep 2008 11:01:26 -0700Subject: test messageThread-Topic: test messageThread-Index: AckPgWoR6Zp07F/cQcq4pSA8qjcr6Q==Message-ID:<50A90E5A65CF0A4581BBC06FAFB9BC4E028F9402D1@exchangeserver>Accept-Language: en-USContent-Language: en-USX-MS-Exchange-Organization-AuthAs: InternalX-MS-Exchange-Organization-AuthMechanism: 04X-MS-Exchange-Organization-AuthSource: exchangeserverX-MS-Has-Attach:X-MS-Exchange-Organization-SCL: -1X-MS-TNEF-Correlator:acceptlanguage: en-USContent-Type: text/plain; charset="us-ascii"Content-Transfer-Encoding: quoted-printableMIME-Version: 1.0 The Word of the Day for September 5 is: wormhole \WERM-hohl\ noun 1 : a hole or passage burrowed by a worm *2 : a hypothetical structure of space-time envisioned as a long thin t=unnel connecting points that are separated in space and time Example sentence: Some science fiction writers speculate that wormholes will become the=intergalactic highways of the future.

Hi,Did you ever find a solution to this? I am having the same problemRemi

Hi,You need to install KB935411 http://support.microsoft.com/kb/935411.Zoran Stamenkovic MVPMCT, MCITP, MCSE, MCDA, ...MCDBA-MCSE

Isnt this an Exchange 2003 patch? We are having issues with Chinese Charsets when the recipient computer is Exchange 2007.

Also having the same issue with Exchange 2007. Has anyone figured out the issue ? Appears to happen with all email with "MIME_QP_LONG_LINE RAW: Quoted-printable line longer than 76 chars This is a multi-part message in MIME format."
