Bulk Update Managers of the Azure AD Users using powershell script

In Azure AD we do not have an option to update the Manager of multiple users. Followig PowerShell script can help us to overcome this repetitive task. 

First we need to create a 'csv' file with following columns

1. User
2. Manager

User column contains the list of User Emails. Manager column will contain the Manager's Email of the respective User.

	#Connect to the Azure AD
	Connect-AzureAD
	#Import the CSV source data
	$data = Import-Csv "C:\Demo\all.csv"
	#Iterate through data
	foreach ($row in $data)
	{
	#Update the Manager
	Set-AzureADUserManager -ObjectId (Get-AzureADUser -ObjectId $row.'User').Objectid -RefObjectId (Get-AzureADUser -ObjectId $row.'Manager').Objectid
	#Log to console
	Write-Host "Updated the user: " $row.'User' " manager to " $row.'Manager' -ForegroundColor Green
	}
