How can I stop Exchange messages line wrapping?

A. By default the Internet Mail Connector will wrap lines ata certain point however it is possible to set it to not wrap as follows:

Below is some extra information on the EnableMimeWrap and UseRTFText registrykeys:

Two registry values exist under the Internet Mail Connector's Parameters keyto provide control over the Internet Mail Connector 's word- wrap and textquoting behavior. The first, UseRTFText, is a DWORD value that specifies ifreply and forward text will be quoted in outgoing non- TNEF. If it is enabled(non-zero), Internet style quoting is applied to reply and forward text byinserting a ">" character before each line. If UseRTFText isdisabled (set to zero or not present), no Internet style quoting is applied.UseRTFText is enabled by default.

The second registry value is EnableMIMEWrap. This is a DWORD value thatcontrols word-wrap in outgoing non-TNEF MIME messages. If it is enabled, linesin MIME messages are wrapped at a fixed column. If EnableMIMEWrap is disabled(and UseRTFText is also disabled), lines are wrapped using quoted printableencoding. MIME enabled readers will unwrap the lines, restoring the originaltext flow, but users with non-MIME readers will see a "=" characterappended to each wrapped line of text. EnableMIMEWrap is enabled by default.

Note that UseRTFText also affects word-wrap. If enabled, text lines in allnon-TNEF messages are wrapped at a fixed column, regardless of the setting ofEnableMIMEWrap. The word-wrap setting for non-MIME messages on the Internet MailConnector properties in Microsoft Exchange Server Administrator program isignored.
