Steps:
- Create a ticket with a customer ( it will the email)
- Answer to the mail with Outlook Desktop( a multiple lines break)
- Look at the response in the discuss frame.
Issue:
In the frame there is much more lines break than in the original mail
Cause:
The format of outlook desktop mail before sanitizing looks like this
```
<div class="WordSection1">
<p class="MsoNormal">Test<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Two break lines<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<div>
```
So when parsing it transforms the ``<o:p></o:p>`` in ``<p></p>``
which adds more lines break when displayed.
Solution:
Remove empty ``<o:...>`` and ``</o:...>`` tags which are specific to outlook desktop before.
