Outlook 2007: Problems with HTML e-mail formatting

[cold.beverage]

Hi,

when I write an e-mail in HTML format with Outlook 2007 the formatting
looks different when sent to someone who is not using Outlook as their
e-mail client.

I will always get an additional empty line with a line-break. This
empty line is not visible in Outlook but in all other e-mail clients.

Is there anything I can do to have the same rendering in all e-mail
clients, including Outlook?

Here's an example:

--- Format in Outlook ---
Hello,

how are you? Bla aldkfjasdlfkj sadflkjsadflk jsdf.
This was a single break.

Regards,
Joe

--- format in other clients when received --
Hello,


how are you? Bla aldkfjasdlfkj sadflkjsadflk jsdf.

This was a single break.


Regards,

Joe
