Email doesn't go to all emails in a email list from SharePoint Provider Hosted Add-in

Question

Hi,

I my on-premise provider hosted add-in, I am sending email notification to a email address list from SQL database.

The problem is, few email addresses never get email from the application. For example, I have 10 email addresses in a SQL table. I am retrieving the emails from database, storing in a list and sending email using SendEmail() Utility. But, 6 email addresses get email, 4 doesn't get. Event that 4 email address don't show up in the TO address box in my sent email. Please see my code below-

EmailProperties emailProperty = new EmailProperties
                    {
                        To = toEmailAddressList,
                        Subject = subject,
                        Body = body
                    };
Microsoft.SharePoint.Client.Utilities.Utility.SendEmail(clientContext, emailProperty );

toEmailAddressList is the list of email address retrieved from the database. Could someone help me out of this?

Thanks in Advance.

Hi Pointtoshare,

Seems like there is nothing wrong with code it's more a users issue then the code. Check the missing users in the user profile service and see for those users exist or not.

Thanks & Regards,

Hi,

If user email exists in user profile(suggested by sharath aluri), try to use below PowerShell to test the issue users could receive email.
