Dear,
When I copy/paste an image in een HTML mail within rouncube and I send it to an emailadress to outlook, the image is not shown and is in error.
In Thunderbird the image is well received. Attached screenshot in outlook and email message.
Let me know if you need any additional info.
Thanks.
Yes. Outlook doesn't support this method. However, in git-master version we added a workaround. Will be available in 0.9.
