In the previous script I provide a way to browse and export Microsoft Teams Information using Graph but this time I have taken that to next level. The script below will allow you to create a Team, Channel, Members, Owners, Tabs and Message, all using Microsoft Graph. The script is created for someone who do not have great knowledge of Graph and may act as starting point. It is not a complete solution but can be use to provision team with basic to medium complexities. Creating Team from Graph and PowerShell may look a bit complex but once you read the graph documentation, It become very easy. The script uses both v1.0 and beta endpoints based on their availability.
The CSV format is as following
ID,TeamName,MailNickName,TeamType,Classification,DeleteExistingTeam,Description,Channels,Owners,Members,Tabs,
1,TeamMXC,TeamMXC,Private,Internal,Yes,Demo Team will provide support,Channel1#Channel2#Channel3,GarthF@tenant.onmicrosoft.com#jerryyasir@tenant.onmicrosoft.com,GarretV@tenant.onmicrosoft.com#abrown@tenant.onmicrosoft.com,C:\temp\CreateTeam-Members.csv,Channel1;Tab1;Tab2#Channel2;Tab3;Tab4
