A lot of people don't like the way 'today' is highlighted in the calendar in Outlook 2013 and Outlook 2016: a thin line at the top of the day, in the same color as the calendar. It's hard to see and blends in with appointments that are not categorized.
Although you can't change the color of the line, a different calendar color might help. I think pink stands out the best, but any color except gray or yellow is more visible.
To change the Calendar color:
- Select the calendar.
- Right-click on the calendar folder and choose Color .
- Select a different color.
Use a Conditional Formatting Rule
If you aren't color categorizing most of your appointments, you can create a conditional filter to change the appointment colors. When appointment colors don't match the calendar color, the day highlight stands out (a tiny bit) better. If you aren't using a lot of recurring or multi-day appointments or meetings, you can highlight appointments that start today (see screenshot at the end of this article).
You can create multiple conditional formatting rules to color-code appointments instead of using categories.
To create a conditional formatting rule:
- Switch to the View tab and click View Settings (on far left)
- Click Conditional formatting button
- Click Add and name your rule.
- Choose a light color. (Unfortunately there isn't an option for White, 'none' is transparent.)
- Click the Condition button to open the Filter dialog.
- On the Advanced tab, type Categories in the Field (or select it from the menu) then select 'is empty' as the condition.
- Optional: Create a second rule that highlights appointments that start today and where the recurrence pattern is empty, in a brighter color. (This rule is less useful if you use a lot of recurring or multi-day appointments or meetings as few appointments will be highlighted 'today'.)
- Select the Today rule and click Move Up to make it the first rule in the list.
- Click OK 3 times to return to Outlook.
Any appointment or event that is not assigned a color will be colorized by the conditional formatting rule. A white or a lighter gray color would blend into the background better but the contrasting colors helps the bar stand out.
After creating the conditional formatting rule and applying it to your view, go to the View tab, Change View and select Save View as a new view. If your current view gets reset, you'll have a copy of the view to apply.
