When configuring, make sure that on the settings of the email account you are connecting it to that security allows for imaps & smtp. I connected to a gmail account so I looked up the settings on my email accounts side to get the right information to put on my mendix application (i.e. for a gmail account the smtp is smtp.gmail.com).
Hi Dominik Kreslo
In the username and password fields you need to generate the password from google and username will be your Gmail ID.
Note that dont use your office wifi some comapanies block the access.
We ended up having to create a branch line prior to downloading the old Email Module with Templates as we kept receiving either java action failures or the inability to send a test email in our local environment. This was after trying to use the Migration Email widget tool as well since we originally used the old Email Template module before pivoting to Email_Connector.
