Finally found and made some adjustments to a Powershell script that checks the number of unread emails from mailboxes in Office 365 / Exchange Online.
And for this to run correctly and scheduled on a Windows box you have to first start these 2 lines with a service account so that you dont fill in the password in the scriptfile.
$UserCredential = Get-Credential
$UserCredential.Password | ConvertFrom-SecureString | Set-Content C:\Temp\scriptsencrypted_password1.txt
If you need more info let me know.
