calendar missing in teams
Let me sum up this thread for people just joining now. If the calendar app is missing from the left of Teams there are two possible reasons
1. (Most Likely) - Teams can not find or access your calendar. It will only access a calendar from the exchange mailbox associated with the users account, if you don't have one, then no calendar. Also if you use Exchange hosted on-premises you will need to have hybrid configured to allow Teams to access that mailbox.

2. (Less Likely) - Someone removed Calendar in an app setup policy assigned to that user. This will hide it from the left menu but it will still be there if you press the ... Menu at the bottom. See Manage app setup policies in Microsoft Teams - Microsoft Teams | Microsoft Docs
richardskates Thank you for posting this. This was exactly my situation. I had disabled Exchange Web Services on my account for testing. Outlook add-ins stopped working, seeing coworker's free/busy was broken, and of course the calendar was missing in Teams. Restoring EWS resolved these issues I'd been having for weeks.
Now my understanding is that EWS only uses basic authentication, if that is true I am wondering how we are supposed to move to only Modern Authentication?
