Change Outlook color schemes
The color scheme in Outlook 2016 does not provide enough contrast for some features, such as highlighting out of office or busy days. This is especially true for the "dark grey" office theme - where the ooo days show up as a whiter shade against a light grey background - impossible to see in the month view. Getting away from the pastel colors would help.
Thank you for reaching out to us at the Disability Answer Desk. This is something that we are currently working on and investigating solutions to improve contrast themes in our software. Our Project Managers are aware of this and we will get back to you as soon as there are more details available.
Again, thank you for reaching out to us. And if in the future, you have further issues, questions, or comments, please let us know.
