Outlook autocleaning my line breaks and screwing up my email format

Start every line with 2 spaces and outlook will be "tricked" into keeping your formatting.

So change

Date of Hire: %HireDate%
Annual Salary: %AnnualIncome%
Reason for Request: %ReasonForRequest%

Name of Voluntary Employee: %FirstName% %LastName%
Total Coverage Applied For:  %EECoverageAmount%
Guaranteed Coverage Portion: %GICoveragePortion%
Amount Subject to Medical Evident: %GIOverage%

to

  Date of Hire: %HireDate%
  Annual Salary: %AnnualIncome%
  Reason for Request: %ReasonForRequest%

  Name of Voluntary Employee: %FirstName% %LastName%
  Total Coverage Applied For:  %EECoverageAmount%
  Guaranteed Coverage Portion: %GICoveragePortion%
  Amount Subject to Medical Evident: %GIOverage%
^^ <--- Two extra spaces at the start of every line

Here is the article I found when researching this problem which goes into a little more depth than my answer.

This answer is on how to "disable" the feature from the Outlook Client.

Go to Tools -> "Options ..."

In the "Preferences" tab click on "Email Options ..."

Uncheck the box "Remove extra line breaks in plain text messages."

Hit OK

FYI:I am using Outlook 2007

Adding "\t\r\n" ( \t for TAB) instead of "\r\n" worked for me on Outlook 2010.

I have always had better luck formatting e-mails as html. You may still have the end-user issue of having to set the client to allow html format, but they are usually more familiar with this since so many e-mails do come html formatted. You also have a little more work on your end adding the html tags, but the end result is much more controllable.

@ephemient also suggests: Send as both HTML and plaintext. Good clients will show the latter, Outlook will show the former, everybody is happy (except the programmer who has to do more work).

Expanding on the Doug L answer, since I think HTML messaging is even more ubiquitous and accepted now than in 2008 when that answer was posted. Here is a little c# snippet to help convert the body and send the message in HTML format:

body = string.Format("<font face='calibri,arial,sans-serif'>{0}<font/>", body.Replace("\r\n", "<br>"));

using (var smtpClient = new SmtpClient() { Host = smtpHost })
using (var msg = new MailMessage(from, emailDistribution, subject, body) { IsBodyHtml = true })
     smtpClient.Send(msg);

Auto cleaning is an outlook feature which removes extra line breaks. You can prevent it by two ways.

First way is to add at least 2 extra spaces before lines while sending the email through code. You can add these extra spaces only before those lines which outlook automatically removes.

Second way is to change outlook setting which will prevent outlook from removing extra line breaks.

I'm seeing the same problem when generating a plain-text email and then reading it with Outlook 2003 SP3. It appears you can avoid the removal process by it by keep the line length under 40 characters. May not always be practical.

Put the text in <pre> Tags and outlook will format and display the text correctly.

i defined it in CSS inline in HTML Body like:

CSS:

pre {
 font-family: Verdana, Geneva, sans-serif;
}

i defined the font-family to have to font set.

HTML:

<td width="70%"><pre>Entry Date/Time:       2013-09-19 17:06:25

this is a new Worklog Entry</pre></td>

My text includes '\r\n' but Outlook 2010 does not render line break. Create tokens of lines delimited by '\r\n' and envelope tokens by HTML Paragraph tags. My Email format is HTML. I am generating HTML Body for my email in the code below.

string[] tokens = Regex.Split(objTickt.Description, "\r\n");
  if (tokens.Length > 0)
  {
     foreach (string line in tokens)
     {
         //htmlTW.WriteEncodedText(objTickt.Description.Replace("\r\n", "\n\n"));
         htmlTW.RenderBeginTag(HtmlTextWriterTag.P);
         htmlTW.WriteEncodedText(line);
         htmlTW.RenderEndTag();
     }
  }

Change your line termination from crlf to either cr or lf.

I suspect that the top of the email uses only cr (or lf), and Outlook expects the rest of the email to follow the same format.
