Can't connect to exchange online using powershell with global admin rights

Question

Hi, I have Global Admin rights on azure

When I try below come powershell code to connect to office 365

$UserCredential = Get-Credential -UserName "******@domain.com" -Message "Username and Password"  
  
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection  
  
Import-PSSession $Session  

I get following error message

Import-PSSession $Session  
New-PSSession : [outlook.office365.com] Connecting to remote server outlook.office365.com failed with the following error message : Access is denied. For more information, see the

Will global admin rights not give me full access on exchange online or do I also need to be part of other groups e.g. exchange admin

You are using an outdated method, which is based on basic authentication, which in turn is likely blocked in your organization or made unusable by requiring MFA. Download the "V2" Exchange Online module and use the Connect-ExchangeOnline cmdlet to connect: https://learn.microsoft.com/en-us/powershell/exchange/exchange-online-powershell-v2?view=exchange-ps
