SetUserPhotoInO365AndAD.ps1

<#
    This script job is to set or update all the company users photo in AD and in O365, and then do a cleanup in your picture folder to remove resigned users photo
    There is a limit on the photo that can be set in AD, thet photo size limit is 100kb. You may need to reduce  the file size on the photes before running this scripts.
    - I'll recommend https://gallery.technet.microsoft.com/scriptcenter/Resize-Image-A-PowerShell-3d26ef68 to resize images using Powershell if needed.

    THE PICTURE FILE HAS TO BE THE SAME NAME AS THE SAMACCOUNTNAME
