Supervisor Posted February 12, 2019 Supervisor Share Posted February 12, 2019 5 hours ago, M Sheraz Iub said: If you have any solution about these errors please solve The error message is telling you that the email address doesn't exist. There's no real solution to this problem, you need to contact the person via another means and confirm that you are writing the correct email address. Also, talk to your IT department who would be able to provide a more detailed log of what is going wrong. Link to comment Share on other sites More sharing options...
