By default, emails you send from your Hotmail account do not include any "Importance" information. But Windows Live Hotmail lets you mark an email as "Important" (with a priority red exclamation mark), or "Not Important" (downward pointing blue arrow). This importance setting for email messages is universally supported among modern email programs and webmail clients (Hotmail, Gmail, Yahoo Mail...) In this tutorial, we will show you how to mark an email as important or not important in Hotmail, and give you a few guidelines on when to use or avoid using the importance option.
Follow these steps to mark an email as important in Hotmail:
In some cases, you may want to explicitly indicate that an email is not urgent: just click on the blue downward pointing arrow in the toolbar, and Hotmail will send this message with "Low Importance", telling your email recipient that follow up can wait.
Once you have marked an email as important or not important, the selected importance will remain visibly selected, as shown on the screenshot. To remove the importance setting from this particular email, simply click once more on the High Importance or Low Importance button, and Hotmail turns off the option.
Just because a feature is available in Hotmail doesn't mean that you should necessarily use it: to offer all the features you expect in a desktop email client like Windows Live Mail, for example, Hotmail includes functionality like importance.
The assumption, when you send an email, is that you respect the recipient's time, and would not necessarily send unimportant emails; by the same token, it is up to the recipient to determine whether an email he or she receives is important or not.
For these reasons, we avoid using the Importance setting.
