One of my most hated things from recent versions of Outlook is the way it edits plain text messages by chopping out supposedly extra line breaks. Inevitably, they’re not extra — they’re there because the sender doesn’t like hitting enter twice between paragraphs — particularly when writing short lists of things.
Outlook does give you the option of restoring the linebreaks it’s taken away by clicking an option near the top of the message. It’s a right pain to have to keep doing it on every message though.
In Outlook XP, I never found a way to turn this off. Maybe it was there, but very well hidden.
Fortunately in Outlook 2003 it’s possible to turn it off for good, though the online help is no help at all at finding it.
Here’s how you do it: Tools / Options / Preferences tab / E-Mail section / click E-mail options. Then find and turn off the checkbox “Remove extra line breaks in plain text messages”.
(Note that after turning it permanently off, it still happens if you’ve been mucking about in a message beforehand, shown the “extra” linebreaks, then hidden them again and saved the message.)
