#set Variable for which Domain Controller to connect to
$Domain_Controller = "MyDC1"

#Check for Creds and ask for them if they aren't found
if (!($Creds)) {$Creds = get-credential -Message "Enter your Domain Admin Creds"}

#Connect to Domain Controller and import a Active Directory Session
$session = New-PSSession -ComputerName $Domain_Controller -Credential $creds
Invoke-Command $session -Scriptblock { Import-Module ActiveDirectory }
Import-PSSession -Session $session -module ActiveDirectory

Test Command

Get-ADuser username

For this you need to have the the MSOnline module installed you can get it by running:

Install-Module MSOnline -verbose

There are two ways to run this and it depends on if you have MFA setup and Trusted locations:
Option 1 – If you do NOT have MFA setup OR you have MFA setup but you are logging in from a “Trusted Location”

#Check for Creds and ask for them if they aren't found
if (!($365Creds)) {$365Creds = get-credential -Message "Enter your Office365 Admin Creds"}

#Make the connection
Connect-MsolService -Credential $365Creds

Option 2 – If you have MFA on and aren’t at a “Trusted Location”

Connect-MsolService

Test Connection

Get-MsolUser -UserPrincipalName user@domain.com

#Set Exchange Server Name
$Exc_Server = "ExchangeServerName"

#Check for Creds and ask for them if they aren't found
if (!($Creds)) {$Creds = get-credential -Message "Enter your Domain Admin Creds"}

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://$Exc_Server/PowerShell/ -Authentication Kerberos -Credential $creds

Import-PSSession $Session

The last Powershell Connection Example I have for you is SCCM. For this one you need to have the SCCM console installed locally or run this from the SCCM server. The console is specific to the version of SCCM you are running, you can get the console install from here \\SCCMSERVERNAME\SCCMConsoleInstaller\consoleinstaller.exe

To connect:

There are a few things to change in the below. Change SITENAME to your SCCM site name in both places, and change SCCM_Server_Name with your SCCM server name.

#Check for Creds and ask for them if they aren't found
if (!($Creds)) {$Creds = get-credential -Message "Enter your Domain Admin Creds"}

Import-Module 'C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\ConfigurationManager.psd1'
New-PSDrive -Credential $Creds -Name "SITENAME" -PSProvider "AdminUI.PS.Provider\CMSite" -Root "SCCM_Server_name" -Description "Primary site"

Connecting to Azure is similar to AzureAD or Exchange online. First, you need the module. Once it is installed, you can now connect. One important thing to note is this AZ module is newer. If you have used the Azure or AzureRM modules in the past you need to remove them with uninstall-module.

Uninstall AzureRM:

Uninstall-AzureRm

Install Module:

 Install-Module az -AllowClobber

Once the module is install you can now connect.

Connect to Azure:

Connect-AzAccount

This will open another window where you can sign into Azure using your credentials.
