6 includes Skype for Business Online () Recently and in an effort to improve PowerShell performance for those connecting to Exchange Online, Microsoft released a series of cmdlets they are referring to as ExO v2. The module has been baptized EXOv2 to indicate a major change compared to the click-to-run module (hereafter referred to as EXOv1), and also because it uses Graph API, just like the AzureAD v2 module. For Exchange Online, make use of the most recent Exchange Online v2 Powershell module. Since we are not the expert about PowerShell scripts, I suggest you post your problem in Microsoft Q&A Forum for more professional assistance. I tried going to Exchange Online Admin portal and run the PowerShell module installation from the 'Hybrid' section, but I get 'Application cannot be started' Here's the output from that: ERROR DETAILS The Exchange Online PowerShell V2 module (abbreviated as the EXO V2 module) uses modern authentication and works with multi-factor authentication (MFA).
Suddenly can't connect to Exchange Online via EXO v2 PS module. Microsoft recently published the new version of the Exchange Online PowerShell module.
