function Connect-O365 
{
	$UserCredential = Get-Credential
	$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://ps.outlook.com/powershell/" -Credential $UserCredential -Authentication Basic -AllowRedirection
	Import-PSSession $Session
	Connect-MsolService -Credential $UserCredential
}
