I have setup ServiceDesk Plus everything is OK only Email notification for technician as well user is not working. I have checked all the settings. After saving settings in Admin=>MailServer Setting=> Incoming it shows settings save successfully and connection with Email server for mailbox is also success.

Screen shot attached for further information about incoming/outgoing email settings.

Moreover I have checked emails working on OutlookWebAccess (OWA) just to troubleshoot that normal email working fine.

Thanks
