There is no connection string for the destination email address

Hi,

I recommend you to verify the following checks;

1) Is the From Address is a valid email address?

2) Are you using SMTP server details or Exchange?

3) If its exchange, then can you open the Exchange web service inside the K2 server browser and see if there any certifications errors.

4) If you are using the SMTP details, then use telenet commands from the k2 server and see if you can send the email from the telnet commands.

Hoep these checks should give some hints for you.

I have had this issue on a few different occasions. 

The first was when we first installed K2. We edited the host file and even the templates in workspace. Ultimately the best fix was to re-run the configuration manager and make sure the SMTP settings were correct. We noticed that during the installation process the configuration manager removed ".com' from the connection string. We fixed this in the configuration manager and didn't have anymore errors.

The second time we received this error was when the "to:" address was not valid. We found that emails are sent differently depending on the method in the form or workflow. For instance if you are sending from a user task in a workflow versus an email event. 

The third time I have had this issue was when saving data from a picker field to a SQL table using the Active Directory SmartObject. When configuring the data source for the picker you can choose the display and the identifier. I found that it was saving the display name to the table so when I was reading the data to send an email to the account saved in that field the destination failed because it was not a valid email address. 

I hope this information helps. 

Thanks,
