Yes I tried the built in sendmail but unfortunately it doesn't work with gmail because the smtp requires authentication. Send mail via CDO doesn't work in windows 10 I'm using a script as described in https://support.smartbear.com/testcomplete/docs/scripting/sending-email-from-scripts.html I use it with gmail account. It works well in windows 7 but doesn't work in windows 10. the windows 10 pc has office 2016. when I try to send an email I get the error: The requested body part was not found in this message. when I do a debug I see that all mMessage fields are empty. I guess this is related to https://support.microsoft.com/en-us/help/2028411/collaboration-data-objects-cdo-1-2-1-is-not-supported-with-outlook-201 What can I do? Please help The code I use: Function SendEmail_Gmail(mFrom, mTo, mSubject, mBody, mAttachment,mpath) Dim smtpServer, smtpPort, userLogin, userPassword Dim authenticationType, useSSL, connectionTimeout Dim schema, mConfig, mMessage mFrom="testcomp.unisfair@gmail.com" smtpServer = "smtp.gmail.com" smtpPort = 25 userLogin = "myaccount" ' e.g. "abc" if the address is abc@gmail.com userPassword = "mypassword" authenticationType = 1 ' cdoBasic connectionTimeout = 30 ' Required by Gmail useSSL = True Err.Clear() On Error Resume Next schema = "http://schemas.microsoft.com/cdo/configuration/" Set mConfig = Sys.OleObject("CDO.Configuration") mConfig.Fields.Item(schema & "sendusing") = 2 ' cdoSendUsingPort mConfig.Fields.Item(schema & "smtpserver") = smtpServer mConfig.Fields.Item(schema & "smtpserverport") = smtpPort mConfig.Fields.Item(schema & "sendusername") = userLogin mConfig.Fields.Item(schema & "sendpassword") = userPassword mConfig.Fields.Item(schema & "smtpauthenticate") = authenticationType mConfig.Fields.Item(schema & "smtpusessl") = useSSL mConfig.Fields.Item(schema & "smtpconnectiontimeout") = connectionTimeout mConfig.Fields.Update() Set mMessage = Sys.OleObject("CDO.Message") Set mMessage.Configuration = mConfig mMessage.From = mFrom mMessage.To = mTo mMessage.Subject = mSubject mMessage.HTMLBody = "email body:"&vbCrLf&mpath&vbCrLf&mBody ' If 0 < Len(mAttachment) Then ' mMessage.AddAttachment(mAttachment) ' mMessage.Attachments=false ' End If mMessage.Fields.Update() mMessage.Send() If Err Then Call Log.Warning("E-mail cannot be sent", Err.Description) SendEMail = False Err.Clear() Else Log.Message("Message to <" & mTo & "> was successfully sent") SendEMail = True End If End Function
