- Product
- Outlook on the Web
- Device & OS
- not provided
- Scenario
- Viewing and managing events in the online Outlook calendar.
- Observed behavior
- The appointment text appears gray and difficult to read, and there is no direct setting available to change the font color to black.
Log in to your Outlook on the Web account and open the Calendar view. Note that Microsoft currently does not provide a native setting to change the specific font color of calendar texts.
Use Color Categories to Improve Readability
Since you cannot change the font color directly, applying vibrant category colors to your appointments will change their background color, significantly improving the contrast and visibility of the default text.
Outlook on the web relies on background color coding rather than font color adjustments to distinguish events. Assigning a category to an event changes the entire block's background color.
Navigate to the Calendar module in Outlook on the web by clicking the calendar icon on the left sidebar.
Right-click on the specific calendar appointment or event that you find difficult to read.
Hover over 'Categorize' in the pop-up context menu. Choose a pre-defined color that provides better contrast (like dark blue or red), or click 'New category' to create a custom color tag.
