Teams - Exchange on-prem

Hi Taen keren,

This is a good place to start

https://docs.microsoft.com/en-us/MicrosoftTeams/exchange-teams-interact
https://docs.microsoft.com/en-us/MicrosoftTeams/exchange-hybrid-organization
https://docs.microsoft.com/en-us/exchange/hybrid-deployment/set-up-office-365-groups

So, ensuring Exchange 2016 CU3+, configuring OAuth, as you said SharePoint licences, configuring Office 365 Groups

My colleague, Shabazz Darr, recently did a blog on the implementation

Hope that answers your question!

Best, Chris
