Can't load Send Email task in portal
We have setup a new production environment with Service Manager 2019 and Cireson products. Now I can't start the Send Email task in the portal. Nothing happens when I click on it. It works fine in our lab environment (also Service Manager 2019) and I have compared the settings in both portal environments under "Admin Settings - Email Settings". The only difference between them is the email address used. The Send Email task works fine from the console in both environments but the portal function only works in the lab.
Has anyone else encountered this problem and can point me in the right direction to resolve this?
