Hi @RywhfyF
Currently, only Teams meetings appear in the Teams calendar. This is by design.
Also, I noticed a piece of feedback in Teams User Voice:
We want to see the Office 365 Group calendar in Teams because this will let you know what's coming up in the group.
And the official has received this feedback, please be patient. To get this feature more quickly, you could vote for it.
Microsoft will always focus on customer’s feedback and experience, some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service. Your time, understanding and cooperation will be highly appreciated.
