Hey developers, Today I’m going to share how to connect Microsoft Teams using OAuth 2.0 token via PowerShell.

Point to be noted!!! 

• Configure an OpenID/OAth application from the Azure AD app (Refrence: https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/openidoauth-tutorial) 
• Open PowerShell as Administrator 
• Install MicrosoftTeams Module
•  Install-Module -Name MicrosoftTeams -RequiredVersion 3.0.0 

Now you can follow following steps:

Get Graph Token using Auth Refresh Token: 

Now Open PowerShell as Administrator:

# Connect-MicrosoftTeams

# Connect-Msolservice: 

Happy Coding!!!
