How to connect to the Exchange Online PowerShell module

Step 1: Installing the Exchange Online PowerShell module

  Copy Set-ExecutionPolicy RemoteSigned
• Install the module: Install Exchange Online PowerShell from the PowerShell Gallery.
  Copy Install-Module -Name ExchangeOnlineManagement
• Verify installation: Learn which version of the module has been installed and where it's installed.
  Copy Get-InstalledModule -Name ExchangeOnlineManagement

Step 2: Load the Exchange Online PowerShell module

• Open a PowerShell window and load the module by running this script:
  Copy Import-Module ExchangeOnlineManagement

Step 3: Connect to the Exchange Online PowerShell module

• Connect using multi-factor authentication (MFA): Connect to Exchange Online PowerShell using MFA.
  Copy Connect-ExchangeOnline -UserPrincipalName
• Connect without MFA: Use the Credential parameter instead of the UserPrincipalName parameter to connect without MFA.
  Copy Connect-ExchangeOnline -Credential (-GetCredential)

Step 4: Importing Exchange modules for on-premises Exchange Server

• For Exchange Server 2013, 2016, or 2019:
  Copy Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn
• For Exchange Server 2010:
  Copy Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010

Limitations of using PowerShell for Exchange management

While PowerShell scripts are fundamental to Exchange management, managing a growing Active Directory and Exchange environment with PowerShell can lead to significant bottlenecks. Here are its limitations:

• Steep learning curve: PowerShell scripting requires in-depth knowledge of cmdlets, parameters, and syntax.
• Limited auditing and tracking: PowerShell does not natively offer detailed audit logs or change tracking unless explicitly scripted and integrated with external logging systems.
• Lacks an intuitive interface: PowerShell lacks an intuitive interface, making even basic tasks complex and time-consuming.

ADManager Plus, an IGA solution with Exchange management and reporting capabilities, allows you to overcome these limitations and easily manage and report on your Exchange environment in just a few clicks.
