Exchange Online PowerShell v2 [General Availability]
The V2 module is now available in the PowerShell Gallery.
The new EXO V2 module contains all the existing Remote PowerShell cmdlets, as well as 9 new V2 cmdlets.
The new module is entirely Modern Authentication based. If you start using this, you are getting off Basic Authentication for your admin tasks, and as you know, that’s a good thing because Basic Auth is going away in Exchange Online.
Then, there are (currently) 9 new REST based cmdlets for the most commonly executed tasks and they are considerably faster and more reliable than their v1 counterparts.
