Many admin tasks in Microsoft 365 go faster with PowerShell: changing a hundred users, building a report or changing a setting that isn't in the admin center. This guide covers which modules you need, how to connect and where to read on.
1. Get ready
- Use PowerShell 7. Read install PowerShell 7 and check your PowerShell version.
- Run PowerShell as administrator if you want to install modules for all users.
- The old MSOnline and AzureAD modules are retired; use Microsoft Graph PowerShell instead.
2. The main modules
| Module | Used for | Install |
|---|---|---|
| Microsoft Graph | Users, groups, licenses, Entra ID | Install-Module Microsoft.Graph |
| Exchange Online | Mailboxes, permissions, mail flow | Install-Module ExchangeOnlineManagement |
| Microsoft Teams | Teams, channels, policies | Install-Module MicrosoftTeams |
| SharePoint Online | Sites, storage, sharing | Install-Module Microsoft.Online.SharePoint.PowerShell |
More detail: the Exchange Online module and the Teams module.
