Installing the Exchange Online PowerShell V2 module

Hi Team -

I would like to ask assistance regarding installing the Powershell V2 module, currently we are using OIM version 8.2.1 but we are getting errors when trying to do the steps given on the technical documentation. 

Install-Module -Name ExchangeOnlineManagement

error: PackageManagement\Install-Package : No Match was found for the specified search criteria and module name

'ExchangeOnlineManagement'. 

Any resolution about this?

Thank you so much.
