I recently implemented sugar for a company using outlook as their CRM before. All went smooth except the import of their data from CSV. They made extensive use of the notes field which I mapped into the description field in the accounts module. The data came in fine but is WAY spaced out. I thought it was a problem with carriage returns in the CSV, so was going to trim them using a quick PHP script. To do this I imported the records to a different instance of sugar running on a linux host. Strange thing was on the linux instance the spacing was not an issue. I viewed the HTML source for the same records and it looks like this:

Linux:
PHONE NUMBER:<br />
<br />
<br />
# OF PEOPLE FOR LUNCH:<br />
ANY FOOD/DRINK RESTRICTIONS:<br />
<br />
SET-UP TIME:<br />
TO BE READY TIME:<br />
<br />
<br />
<br />
<br />
PHYSICIANS:<br />
<br />

Windows:
PHONE NUMBER:<br />
<br />
<br />
<br />
<br />

Both versions are running Version 5.5.0 (Build 6653) CE. Both are running on Apache. The windows instance was installed using the windows stack installer with MySQL.

If any more information would be helpful or screenshots to show what it looks like I can get those and post them too.
