it happens to me any solution please?
Which email server are you using? Gmail?
I use the cloud version. Great program. I’m having problems with SMTP. I use my own website server using WebMail. In SMTP Host if I use “smtp.my-site.com.au” I get an immediate “fail” error. If I use only “my-site.com.au” I get a 504 time out message. I have spent two days with “my-site” support on various configurations of Manager Email setup to see if one would work. I am told the latest email setup is correct. As an experiment, I used only “gmail.com” instead of “smtp.gmail.com” I got an error as expected. I don’t want to use Gmail for Manager for unrelated technical matters or Live.com and especially Yahoo.
Email sending format
Hostname: my-site.com.au Port: 587
I have the same problem. I have entered email credential and the test message send OK but the document view fails. Did you ever find a solution?
You can either turn on “Less Secure Apps” setting in your google account or use app specific password.
