WinCCFlex2005 email notification of alarms

Hello,

I have been trying to set this option in one WinccFlex project. I set up SMTP both in the project and in WinCCFlex internet settings of my laptop (where the RT is running at the moment) but I always have warrning 70037 cannot send e-mail. I think I did everything by the book. I checked SMTP with our IT guy and it is OK.
What can be wrong?

Thanks in advance

Hello to all,

I tried yesterday evening back home and it works . So it must be something that is blocking email sending here in the office. I will double chek it with IT.
