New-Exopssession: Create PowerShell Session Is Failed Using OAAuth

It is important that PowerShell supports OAuth when accessing the Exchange Online management console. If you get an error message such as “New Exopssession: Create Powershell Session is Failed using OAAuth”, then you should verify that the PowerShell module supports OAuth.

You must have the appropriate permissions and account to use the new-exopssession cmdlet. For example, if the exchange online management console is set to use Windows authentication, the new-exopssession command will fail to connect. When the new-exopssession cmdlet is run, it will prompt for a user name and password. It will then connect with the Exchange Online PowerShell Server. This step requires administrator privileges.
