Using New Outlook on Windows for personal email, calendar, and contact management
Hi @Anna Gorton
Being able to distinguish calendar categories is an important accessibility need, not simply a color preference.
In new Outlook, you can give each category a clear, descriptive name through Settings > Accounts > Categories. You can also use the Filter option in Calendar to display events by category instead of relying only on colors.
Regarding the unreadable emails in classic Outlook, could you confirm whether the messages display normally in your email provider’s webmail and whether the third-party account is configured using IMAP or POP? This can help determine whether the behavior is related to account synchronization or how classic Outlook displays the messages.
As there is currently no documented option to create custom high-contrast category colors, I recommend sharing this accessibility concern directly with Microsoft through Send feedback · Community.
