Access denied error on connecting to office365

Question

I'm trying to connect to Office365 with Powershell.
$username = "[email protected]"
$password = "password"
$secure_password = $password | ConvertTo-SecureString -AsPlainText -Force
$credencial = New-Object System.Management.Automation.PSCredential ($username, $secure_password)
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://ps.outlook.com/powershell/" -Credential $credencial -Authentication Basic -AllowRedirection -ErrorAction Stop -WarningAction SilentlyContinue
Import-PSSession $session -AllowClobber | Out-Null
Problem is that on Powershell console on local PC and on server it works fine without any errors, but when I'm trying to run this with PHP:
<?php
$command = 'powershell -File "'.dirname(__DIR__).'\\ps\\test.ps1"';
exec($command, $output);
print_r($output);
?>
I'm getting error, that "Access is denied":
Array
[0] => New-PSSession : [pod51047psh.outlook.com] Connecting to remote server pod51047p
[1] => sh.outlook.com failed with the following error message : Access is denied. For

Any suggestions what I'm doing wrong? Are there other ways to run this Powershell script with PHP?

Hello Ludek,
I had to take ownership and then change persmissions to full. The problem did not go away however. As I noticed that the register key mentioned did not contain any subkeys I tried to remove it. This again failed because of persmission denied error. Funnily some subkeys suddenly showed up. I took ownership, changed permissions and tried again. Lo and behold the subkeys I tried to delete (and in which no subkeys were visible) suddenly showed more subkeys. At this point I stopped fearing that I was damaging the client's computer. The subkeys were related to the RAS server. Does that say anyting to you?
