What rule can you create in view settings to color code messages from a particular sender?

The color coding isn’t just intended to emphasize certain emails but it can also be used to deemphasize certain emails such as newsletters or emails you are only a CC or BCC recipient of.

You may actually already know Conditional Formatting without realizing it as it is for instance also being used to:

• Show unread emails in a blue and bold font.
• Show expired emails and completed tasks in a grey and strikethrough font.
• Show overdue emails and tasks in a red font.

The “Conditional Formatting” feature may look complex at first but creating color coding rules is actually fairly easy and quite powerful when used the right way.

This guide will help you on your way to get yourself familiar with the Conditional Formatting options with 8 color coding examples which might be useful to you as well.

Conditional Formatting Tips & Tricks

The tips and tricks below will help you better understand how the Conditional Formatting feature works and generate its color coded view.

• You can sort the rules by using the “Move Up” and “Move Down” buttons. The higher listed rules takes precedence over the lower ones. A lower listed rule can append the formatting of a higher listed rule if the formatting is not defined.
  • For instance, when in a higher listed rule the font color is set to “Auto” the color of a lower rule will apply. However, if the higher listed rule has a color defined, the lower rule will not “overwrite” this color.
• Specifying names of senders or recipients in a Conditional Formatting rules can be a bit tricky; The name must exactly match the name as displayed in the From field of the message. Better is to create the rule based on the e-mail address. If you are in an Exchange environment, you can simply add the names as listed in the Global Address Book of your company.
• The Conditional Formatting rule only applies to the folders which use the same view. To apply your custom view to other folders see: Applying custom views to all folders at once.
• If the rule doesn’t do what you expect it to do once created, you might want to try to remove or even isolate statements (by creating a separate rule for that statement) to find out where things go wrong.
• Do not add too much color to your mailbox or the organizing effect gets lost (but you’ll be left with a nice rainbow though
  
  ).
