ExchangeOnlineManagement 3.10.1 released

Hi All,

A few days ago, Microsoft has released a new Version of ExchangeOnlineManagement PowerShell Module.

PowerShell Gallery ExchangeOnlineManagement 3.10.1

Release Notes v3.10.1:

Fixed certificate-based authentication (CBA) flow bugs and few other minor performance issues.

Installation

Check the installed Module and what’s available from the PowerShell Gallery

Get-InstalledPSResource -Name ExchangeOnlineManagement -Scope CurrentUser
Find-PSResource -Name ExchangeOnlineManagement

Let’s uninstall the old Module and install the new Module

Uninstall-PSResource -Name ExchangeOnlineManagement -Scope CurrentUser -SkipDependencyCheck
Install-PSResource -Name ExchangeOnlineManagement -Scope CurrentUser -Repository PSGallery
Get-InstalledPSResource -Name ExchangeOnlineManagement -Scope CurrentUser

Some basic tests

Connect-ExchangeOnline -ShowBanner:$false
Get-Mailbox -Identity a.bohren@icewolf.ch
Disconnect-ExchangeOnline

There where some issues with the Application Authentication - they seem now be fixed

#Connect-ExchangeOnline with AppId and Certificate

$AppID = "9d0e452e-b407-4901-9ed1-aacaeed63f11"
$CertificateThumbprint = "A3A07A3C2C109303CCCB011B10141A020C8AFDA3"
$TenantId = "icewolfch.onmicrosoft.com"
Connect-ExchangeOnline -AppId $AppID -CertificateThumbprint $CertificateThumbprint -Organization $TenantId -Showbanner:$false
Get-Mailbox -Identity a.bohren@icewolf.ch

I’ve used my M365PSProfile Module to update the most important M365 Modules - find the Documentation here: GitHub Documentation
