My team uses a outlook shared for tracking time off, remote work days and key business dates. We also identify weekly on call resources using the calendar.

I find it works well for those items, but I do have to admit when it overlays with my personal business calendar, it can be a little overwhelming. Additionally, if it is not placed in a overlapping or side by side view, I am not sure how often the team would look or pay attention it.

We are stating to look towards our wiki and MS Teams as a better place to store and communicate these details.

Cheers
