I am having this same problem about the event notification email not being sent - and trying to send an email from the "Edit event --> Enrollment --> Email All Enrolled Users" does not work.
I have enabled the Scheduler for the Events Module from the "Host --> Schedule --> DotNetNuke....Events --> Settings --> Schedule Enabled" area, and I'm getting 2 errors from the Log Viewer:
----------------------------------------------------------------------------------
1.)
"Scheduler Event Failure" with detail:
TYPE: DotNetNuke.Modules.Events.EventNotification
EXCEPTION: The parameter 'to' cannot be an empty string. Parameter name: to
2.)
"Scheduler Exception" with detail:
InnerException: The parameter 'to' cannot be an empty string. Parameter name: to
FileName:
FileLineNumber: -1
FileColumnNumber: -1
Method:
StackTrace:
Message: System.ArgumentException: The parameter 'to' cannot be an empty string. Parameter name: to at System.Net.Mail.MailMessage..ctor(String from, String to) at DotNetNuke.Services.Mail.Mail.SendMail(String MailFrom, String MailTo, String Cc, String Bcc, MailPriority Priority, String Subject, MailFormat BodyFormat, Encoding BodyEncoding, String Body, String Attachment, String SMTPServer, String SMTPAuthentication, String SMTPUsername, String SMTPPassword) at DotNetNuke.Modules.Events.EventNotification.SendEventNotifications() at DotNetNuke.Modules.Events.EventNotification.DoWork()
3.)
I am also getting this error from the Scheduler History on the Events Schedule:
Event Notification failed.System.ArgumentException: The parameter 'to' cannot be an empty string.
Parameter name: to
at System.Net.Mail.MailMessage..ctor(String from, String to)
at DotNetNuke.Services.Mail.Mail.SendMail(String MailFrom, String MailTo, String Cc, String Bcc, MailPriority Priority, String Subject, MailFormat BodyFormat, Encoding BodyEncoding, String Body, String Attachment, String SMTPServer, String SMTPAuthentication, String SMTPUsername, String SMTPPassword)
at DotNetNuke.Modules.Events.EventNotification.SendEventNotifications()
at DotNetNuke.Modules.Events.EventNotification.DoWork()
----------------------------------------------------------------------------------
Can anyone give me some clues, or tips on things to try? Also, I am able to send mail from the system, e.g., using the newsletter function of my portal - so I'm sure that SMTP is working for the portal.
Thanks in advance for any help!

I have DNN 4.3.5 and get this error when sending any Event notifications:

I have no problem testing SMTP settings or using the newsletters/bulk emal.

I'm having the same problems as everyone else in this thread. Detailed info:
DNN 4.3.5
Events Module 3.02.00
Sending Newsletters works without a hitch.
Scheduler is enabled under Host -> Schedule -> DotNetNuke.Modules.Events.EventNotification, DotNetNuke.Modules.Events
Notifications do not get sent out. The following error occurs in the Log Viewer:

The above messages would indicate that there is nothing in the "to" field, however both test users that enrolled in the event had valid addresses assigned in their profiles.
Sending messages to Enrolled members through the Events module also generates errors:
InnerException: The SMTP host was not specified.
And when I checked the checkbox to attach the event, the following error was generated:
InnerException: The process cannot access the file
'C:\Inetpub\wwwroot\dotnetnuke\Portals\15521ee264-4781-4942-abf6-a1b7a199e570.vcs'
because it is being used by another process.
The functionality available in this module is phenomenal. Extremely useful for the types of things I want to do, however these notification/email issues are standing in the way. Any assistance would be greatly appreciated.

Ok everyone, I have done a lot of work to this module, and I have the Enrollments working. There is a bug in the Events code, so I did a couple things:
1.) I converted the project to work within the App_Code folder, this required modifying the CreateProvider() method in the DataProvider code to use the new .NET 2 way of querying for the Assembly, instead of referring to the DLL as it did when it was pre-compiled. You also have to modify your web.config to use the codeSubDirectories, dividing up the events module into three folders. If anyone wants to get a .zip file of files, post here or send me an email. It is important to get the correct files within the correct directories together.
2.) Separate from the App_Code thing (this file will work if you re-compile the original project, OR if you do the above App_Code thing), the method Mail() in EditEvents.ascx.vb calls the wrong method in the DotNetNuke.Services.Mail class. I simply modified the method to correctly query the DNN framework for the SMTP settings. Everything now works as advertised. Code is posted below all this
Note: I just fixed this - I've not checked to see if Notifications work yet, but I'll post back when I get it checked.
Oh, and those of you with a problem with the "to" string, I had that, then I traced the code and realized I hadn't set the email address for the SuperUser account, I'm guessing you logged in as Host or Admin, and then didn't set your email address in the SuperUsers Accounts section. That'll give you that error.
OK here is the code are you need to modify in EditEvents.ascx.vb (I included the whole method, so just copy and paste):
Private Sub Email(ByVal Selected As Boolean)
Dim item As DataGridItem
Dim subject As String
Dim body As String
Dim attachment As StringBuilder
Dim oVEvent As New vEvent
Dim objCtlUser As New UserController
Dim objModUser As New UserInfo
Dim objEventUser As New UserInfo
Dim fp As System.IO.StreamWriter
Dim filepath As String = ""
objModUser = objCtlUser.GetUser(PortalId, UserId)
Dim useremail As String = objModUser.Membership.Email
Dim objEnroll As EventSignupsInfo
Dim objportal As DotNetNuke.Entities.Portals.PortalInfo = New DotNetNuke.Entities.Portals.PortalController().GetPortal(PortalId)
Dim SMTPServer As String = Nothing
Dim SMTPAuthentication As String = Nothing
Dim SMTPUsername As String = Nothing
Dim SMTPPassword As String = Nothing
' SMTP server configuration
If Convert.ToString(Common.Globals.HostSettings("SMTPServer")) <> "" Then
SMTPServer = Convert.ToString(Common.Globals.HostSettings("SMTPServer"))
End If
If Convert.ToString(Common.Globals.HostSettings("SMTPAuthentication")) <> "" Then
SMTPAuthentication = Convert.ToString(Common.Globals.HostSettings("SMTPAuthentication"))
End If
If Convert.ToString(Common.Globals.HostSettings("SMTPUsername")) <> "" Then
SMTPUsername = Convert.ToString(Common.Globals.HostSettings("SMTPUsername"))
End If
If Convert.ToString(Common.Globals.HostSettings("SMTPPassword")) <> "" Then
SMTPPassword = Convert.ToString(Common.Globals.HostSettings("SMTPPassword"))
End If
For Each item In Me.grdEnrollment.Items
If CType(item.FindControl("chkSelect"), CheckBox).Checked Or (Selected = False) Then
objEnroll = Me.objCtlEventSignups.EventsSignupsGet(CType(grdEnrollment.DataKeys(item.ItemIndex), Integer))
' Email Requesting User
subject = txtEmailSubject.Text
body = "<p><a href="
body += NavigateURL(TabId, "Details", "mid=" & ModuleId, "ItemID=" & objEnroll.EventID.ToString(), "selecteddate=" & objEnroll.EventDateBegin.ToShortDateString) & ">"
body += String.Format(Localization.GetString("EnrollMessage", LocalResourceFile), objEnroll.EventName, objEnroll.EventDateBegin.ToShortDateString, objEnroll.EventTimeBegin.TimeOfDay.ToString)
body += "</a></p>"
If Me.chkAttachment.Checked Then
body += Localization.GetString("Attachment", LocalResourceFile)
attachment = oVEvent.GetOutlookEvent(objEnroll.EventID, Context, objEnroll.EventDateBegin)
' Create Attachment File
filepath = Request.MapPath(objportal.HomeDirectory) + Guid.NewGuid.ToString + ".vcs"
fp = System.IO.File.CreateText(filepath)
fp.Write(attachment)
fp.Close()
body += txtEmailMessage.Text
body = System.Web.HttpUtility.HtmlDecode(body).Replace(vbCrLf, "").Trim
DotNetNuke.Services.Mail.Mail.SendMail(useremail, objEnroll.Email, "", "", MailPriority.Normal, subject, MailFormat.Html, System.Text.Encoding.UTF8, body, filepath, SMTPServer, SMTPAuthentication, SMTPUsername, SMTPPassword)
If System.IO.File.Exists(filepath) Then
System.IO.File.Delete(filepath)
End If
Else
body += txtEmailMessage.Text
body = System.Web.HttpUtility.HtmlDecode(body).Replace(vbCrLf, "").Trim
DotNetNuke.Services.Mail.Mail.SendMail(useremail, objEnroll.Email, "", "", MailPriority.Normal, subject, MailFormat.Html, System.Text.Encoding.UTF8, body, "", SMTPServer, SMTPAuthentication, SMTPUsername, SMTPPassword)
End If
End If
Next
End Sub
