Hi All, I upgraded a Windows 2008 R2 server to Windows 2012. I made a backup of 3CX, uninstalled 3CX and downloaded and installed 3CX SP3. I restored from backup and everything works with the exception of emails. No emails work...not for system notifications, phone provisions, missed calls, etc. I had this same issue when testing 3CX in the fall when it was not officially supported on Windows 2012. If I roll back to a snapshot of Windows 2008 R2, everything is fine. I am convinced the issue is with Windows 2012 and would love to help resolving the issue. My client wants to run this on Windows 2012, so I would hate to move things back to 2008 R2, but they are dependant on the "mail notification on missed call" feature. Additionally, there are no GPOs or policies that would be causing this issue. Thoughts?
