Format e-mail by create from other app

I’m using M-Files DMS software. I have many functions in M-Files there create a new message in default mail client and fill links or documents as attachment.

I have the message templates and signatures in eM Client. The template is OK by manually using.
But if M-Files create a new message, there are’nt set the correct properties - font and size, color, the format of signature.

In Settings - Templates and Signatures is checked option “Apply a template and signature to messages sent from other applications”. So, content is OK, format no.

Thanks for tip.
Best Regards

There was another post recently (can’t find it now, sorry) where a similar issue was solved by setting the reply format to HTML

Maybe worth trying that.

Found the other thread:

Thanks, I changed automatic detection to HTML and all is OK - creating message is formated.
