Currently the Dynamics 365 E-Mail Editor only allows to insert images in the E-Mail body via a link meaning images have to be stored online. Local images can only be inserted as attachment. This is not really productive if you need to add local images that must be in the context of the text like step by step instructions for answering a case or screenshots with descriptions.
Allow users to copy & paste images from their computer in the Dynamics 365 E-Mail body and/or to upload images from the computer to Dynamics 365 and insert it in the E-Mail body. This functionality is normally available in E-Mail editors like outlook, gmail etc.
Added value for Dynamics 365 users & customers:
For the dynamics 365 user it is much easier to insert a image if he can just copy & paste to the body or upload it in Dynamics 365 and then add in the body instead of uploading the image on a different web storage and search for the right link to be able to insert the image.
On the customers side the images are directly visible inside the E-Mail with the right flow and context. The customer can see all images directly in a structured way instead of having to open each image individually from an unstructured attachment list. This makes it easier for the customer to read the E-mail and understand the content and and finally increases the customer satisfaction.
This functionality would be useful for many Dynamics 365 users and was already suggest multiple times.
Here are older ideas that asked for the same thing:
MS Dynamics CRM does not support pasting images in outgoing e-mails
Easier allow images in Direct E-mail
