    inOutlook_Object.Value, 
    "<p><b>Hy bruno</b></p>
    <p> This is my message</p>
    <p>Best regards</p>
    "
) 

Send Mail with Importance Markup

Add Importance Attribut to Options. There is 3 Importance levels: Hight, Low, Normal

Office365Outlook.SendEmailV2(
    inOutlook_To.Selected.Mail, 
    inOutlook_Object.Value, 
    inOutlook_Message.Value,

        Importance:"High"

    inOutlook_Object.Value, 
    inOutlook_Message.Value,
    {
        ReplyTo:"me@me.com"
    }
) 

Send Mail with Rich Text Editor

1. Add a Rich text editor control (Insert > Rich text editor)

2. Rename this control with inOutlook_HtmlMessage

Now, change the OnSelect property :

Office365Outlook.SendEmailV2(
    inOutlook_To.Selected.Mail, 
    inOutlook_Object.Value, 
    inOutlook_HtmlMessage.HtmlText
) 

3. Compose your message in PowerApps Page and Click Send Button. You could also paste a image in Rich Text Editor

To send a Email with Image included

To send an image directly included in the Mail (forcing the image to be displayed) without the risk of Outlook blocking it, you need to include a Base64 encoded image in Html Code
To encode an image, visit https://www.base64-image.de/

Office365Outlook.SendEmailV2(
    inOutlook_To.Selected.Mail, 
    inOutlook_Object.Value, 
    "<p><b>Hy bruno</b></p>
    <p> This is my photo</p>
    <img src='data:image/png;base64,[COPY_PAST_YOUR_BASE64_IMAGE]'>
    <p>Best regards</p>
    "
) 

The result :

Send Mail with Attachments by Attachment Control

The Attachments control is not natively available. You must copy The Attachment Control from a PowerApps Form linked to a SharePoint list.

Even Copy as Code doesn’t work !

Office365Outlook.SendEmailV2(
    inOutlook_To.Selected.Mail, 
    inOutlook_Object.Value, 
    inOutlook_Message.Value,
    {
        Attachments: ForAll(
            inOutlook_Attachment.Attachments,
            {
                ContentBytes: Value,
                Name: Name
            }
        )
    }
) 

Send Mail with SharePoint Attachment

With a Item from a SharePoint List, you can attach a document from Attachment Field

Office365Outlook.SendEmailV2(
    inOutlook_To.Selected.Mail, 
    inOutlook_Object.Value, 
    inOutlook_Message.Value,
    {
        Attachments: 
        {
                ContentBytes: First( LookUp( MyList, ID=1).Attachments).Value,
                Name: First( LookUp( MyList, ID=1).Attachments).DisplayName
        }
    }
)
