'Connect-MsolService' Is Not Recognized As The Name Of A Cmdlet

Answer :

I had to do this in that order:

Install-Module MSOnline
Install-Module AzureAD
Import-Module AzureAD

All links to the Azure Active Directory Connection page now seem to be invalid.

I had an older version of Azure AD installed too, this is what worked for me.
Install this.

Run these in an elevated PS session:

uninstall-module AzureAD  # this may or may not be needed
install-module AzureAD
install-module AzureADPreview
install-module MSOnline

I was then able to log in and run what I needed.

This issue can occur if the Azure Active Directory Module for Windows PowerShell isn't loaded correctly.

To resolve this issue, follow these steps.

1.Install the Azure Active Directory Module for Windows PowerShell on the computer (if it isn't already installed). To install the Azure Active Directory Module for Windows PowerShell, go to the following Microsoft website:

Manage Azure AD using Windows PowerShell

2.If the MSOnline module isn't present, use Windows PowerShell to import the MSOnline module.

Import-Module MSOnline 

After it complete, we can use this command to check it.

PS C:\Users> Get-Module -ListAvailable -Name MSOnline*


    Directory: C:\windows\system32\WindowsPowerShell\v1.0\Modules

Update:
