I was trying to send mail through one my smtp server and it was worrking fine, I wanted to experiment the same for gmail with "SMTP.gmail.com",I tried changing the port from 25 to 587 to make it work for gmail. I was going through one of the links "http://gotcal.com/index.php/2010/06/smtp-mail-functionality-in-pre-dynamics-nav-5-version/"
; and run the application mentioned in the link. it did not work and suddenly I see that earlier working smtp server is not working for sending mails from navision , I get the message "The message is for C/AL programers could not invoke the memeber send. The OLE control or automation server returned an unknown error code". I have NAV 2009 SP1 running in my system.
I tried uninstalling and reinstalling but before experimenting with system registers, I would like to hear from you. Please comment
