You Should Know:
1. Installing Required Modules
To manually install Microsoft 365 PowerShell modules, use:
Install-Module -Name ExchangeOnlineManagement Install-Module -Name Microsoft.Graph Install-Module -Name MicrosoftTeams Install-Module -Name SharePointPnPPowerShellOnline
2. Connecting to Microsoft 365 Services
For basic authentication (without MFA):
Connect-ExchangeOnline -UserPrincipalName [email protected] Connect-MgGraph -Scopes "User.Read.All" Connect-MicrosoftTeams -AccountId [email protected]
For MFA-enabled accounts:
Connect-ExchangeOnline -UserPrincipalName [email protected] -UseMultiFactorAuthentication Connect-MgGraph -Scopes "User.Read.All" -UseDeviceAuthentication
For certificate-based authentication:
Connect-ExchangeOnline -AppId <AppID> -CertificateThumbprint <Thumbprint> -Organization <TenantID> Connect-MgGraph -ClientId <AppID> -TenantId <TenantID> -CertificateThumbprint <Thumbprint>
3. Verifying Connections
Check active sessions:
Get-PSSession | Select-Object State, ComputerName Get-MgContext | Select-Object Scopes, ClientId
4. Managing Exchange Online
List all mailboxes:
Get-Mailbox
Set mailbox permissions:
Add-MailboxPermission -Identity [email protected] -User [email protected] -AccessRights FullAccess
5. Managing Azure AD via Microsoft Graph
List all users:
Get-MgUser
Get a specific user’s details:

What Undercode Say:
PowerShell remains a dominant tool for IT administrators managing Microsoft 365. Automating connections to multiple services via a single script enhances efficiency, especially in large-scale environments. Certificate-based authentication and MFA support ensure security compliance.
For Linux admins working with hybrid environments, consider using `curl` or `az cli` for Azure integrations:
az login --service-principal -u <app-id> -p <password-or-cert> --tenant <tenant-id>
For Windows event log checks:
Get-EventLog -LogName Security -Newest 50
For network diagnostics:
ping office365.com traceroute outlook.office365.com
Expected Output:
A fully automated, secure, and efficient way to manage Microsoft 365 services via PowerShell with minimal manual intervention.
