    I upgraded to the most recent version (15.5.8801.3) over the weekend. Everything works fine except email notifications. I can't use my email server only the 3CX SMTP server. Any ideas why? I have the Professional perpetual license.

    Windows 10 Pro (15.5.8801.3) same issue also professional perpetual license.

    Using a simple custom smtp server (port 25) to our exchange 2010, upon testing the "new email settings interface" I receive the 'No compatible authentication mechanisms found'.

    3cxSystemService.log
