Exchange Online PowerShell V2 module

The Exchange Online PowerShell V2 module (abbreviated as the EXO V2 module) uses modern authentication to connect to the Exchange-related PowerShell environment in Microsoft 365.

Some key points about the EXO V2 module:

  • Download from PowerShell gallery
  • Run the module from Windows PowerShell and Windows PowerShell ISE
  • Single cmdlet Connect-ExchangeOnlinesupports both MFA and non-MFA accounts
  • EXO V2 cmdlets are REST API-based which are much faster and more reliable
  • Older cmdlets are backward compatible
  • All versions of the EXO V2 module are supported in Windows PowerShell 5.1. PowerShell 7 on Windows requires version 2.0.4 or later of the EXO V2 moduloke

Install Exchange Online PowerShell V2 module

Before we can install the Exchange Online PowerShell V2 module, we need to set up the system.

Start the following commandlets

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Install-Module PowershellGet -Force

Update-Module PowershellGet

Set-ExecutionPolicy RemoteSigned

Install-Module -Name ExchangeOnlineManagement

By default, we can’t install scripts. To require all PowerShell scripts that you download from the internet are signed by a trusted publisher, run PowerShell as administrator, and run the cmdlet. Press Y and press Enter.

Troubleshooting

O365 currently supports only TLS 1.2 protocol. The PowerShell command we use to connect to exchange online may not using that protocol and hence the handshake may be failing.

1. Error Acquiring Token

  • If you see the issue the following message in PowerShell, then the issue is related to TLS 1.2 protocol:

 To Solve the issue please follow the below steps:

  1. Backup the current Registry on the CE Server.
  2. Make the below changes in the Registry on the CE server
  3. TLS 1.2 registry key

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727]
   "SystemDefaultTlsVersions" = dword:00000001
   "SchUseStrongCrypto" = dword:00000001


[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
   "SystemDefaultTlsVersions" = dword:00000001
   "SchUseStrongCrypto" = dword:000000013

        4. Stop and Restart CE services and check if the issue persists.
       5. If the issue persists, reboot the CE server and check again if the issue persists.

2. If you see the following message in cloud extender config tool - Unable to authenticate the following service account


Add this registry Key - TLS 1.2 registry key

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727]
   "SystemDefaultTlsVersions" = dword:00000001
   "SchUseStrongCrypto" = dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
   "SystemDefaultTlsVersions" = dword:00000001
   "SchUseStrongCrypto" = dword:000000013

    4. Stop and Restart CE services and check if the issue persists.
    5. If the issue persists, reboot the CE server and check again if the issue persists.
