Somewhat confusingly, Microsoft refers to the module as “ Exchange Online PowerShell V2” while the version of the generally available module is 1.0.1 (Figure 1). Upgrading to the Generally Available VersionĪfter being in preview since Ignite, the new cmdlets are now generally available and the module can be downloaded from the PowerShell Gallery. In a nutshell, the old cmdlets are slow and unreliable in large tenants. The older Remote PowerShell implementation works well with small numbers of mailboxes but begins to suffer problems as mailboxes mount into the thousands. These cmdlets have been part of Exchange PowerShell since its introduction in Exchange 2007.Īpart from being some of the most used cmdlets, the common thread linking the nine chosen cmdlets is that they often retrieve large amounts of mailbox data. The big change was the introduction of nine cmdlets built on REST APIs to replace older cmdlets like Get-Mailbox and Get-MailboxStatistics. This will launch your browser so that you can authenticate, including responding to the MFA prompt, and then once you’ve logged in you can close the browser and continue the rest of your PowerShell session in the Terminal.Last November, Microsoft announced a refresh of the Exchange Online PowerShell module at the Ignite 2019 conference. Once the EXO V2 module is installed, you can then connect to Exchange Online by simply typing Connect-ExchangeOnline. You may, if this is the first time you’ve installed any modules in PowerSHell, also need to set the Execution Policy to allow remote signed modules via Set-ExecutionPolicy RemoteSigned Then, in the PowerShell session, install the EXO V2 module by typing Install-Module -Name ExchangeOnlineManagement Then, once you have downloaded and installed it, launch PowerShell as root e.g. Head on over to the GitHub repository and download the latest release that isn’t a Preview Release (look for the green Latest release tag)

Connecting to Exchange Online with Modern Auth required a whole new PowerShell module, and that module was only available on Windows.įortunately, Microsoft have ported the EXO V2 module to macOS and Linux, so now it’s possible to connect to Exchange Online from non-Windows platforms and use Modern Auth.įirst, you need to make sure you have an up-to-date version of PowerShell installed. While there were a couple of workarounds to connect using Basic authentication, until recently there was no solution for Modern Auth. For quite some time, it has not been possible to connect to Office 365 / Exchange Online with PowerShell, if your tenancy is using Modern Authentication (i.e.
