New Teams Calendar

Question

Now that we are forced to use the new Teams calendar, will there be an update to allow for customization. In dark mode it is very difficult to see the lines separating the days and hours. I would love to see some more customizable options like line weight and color. In my opinion the new calendar is very hard to differentiate the days and times and I cant even tell what part is highlighted for my working hours. .

Hi @Ingardia, Austin 

Welcome to the Microsoft Q&A forum. 

Thank you so much for taking the time to share your experience with the new Teams calendar. I truly appreciate the clarity and thoughtfulness of your feedback. I can imagine how difficult it must be when a design shift impacts your daily workflow, especially when dark mode should ideally make things easier, not harder. The faint grid lines, subtle hour markers, and low‑contrast highlights you mentioned can absolutely affect visibility and comfort, and your perspective on this is incredibly valuable. 

Currently, Microsoft hasn’t announced any plans to introduce deeper visual customization options in the new Teams calendar, for example, adjusting grid‑line color, line thickness, or contrast levels. Instead, the updates released so far focus more on structural improvements, such as new time‑scale controls, saved calendar views, and additional scheduling settings. Unfortunately, these enhancements don’t currently address the visibility concerns you’ve mentioned.

Currently, there is no specific information available regarding updates to the new Teams calendar that would allow for customization options such as line weight and color in dark mode. Your feedback about the visibility of the lines separating days and hours is valuable, and it may be considered for future updates. However, as of now, the details on any upcoming features or enhancements related to customization in the Teams calendar have not been provided in the available documentation.
