Just a quick heads up to let you know about a known issue you may run into after upgrading to System Center Operations Manager 2007 R2. After you upgrade from Operations Manager 2007 SP1 to Operations Manager 2007 R2, alert descriptions that are formatted with HTML tags such as the <br> or <hr> tag are not displayed correctly.
In previous versions of Operations Manager, the alert description was parsed as an HTML page. In Operations Manager 2007 R2, the ability to format alert descriptions by using HTML tags was removed due to security issues; the HTML tags are now shown as text.
In Operations Manager 2007 R2, you can use carriage returns directly within the alert description instead of the HTML tags.
We've updated the TechNet documentation/Release Notes to reflect this as well:
