I am using Send an Email (V2) to send email with Embedded Images using CID as my IMG source.
- Image are retrieved from Sharepoint or OneDrive using "Get File content using path" action
- Place the image as an attachment to the email (avoid using <space> in the file name)
- File name will then be called out inside the Email's body using <img src="cid:{filename}" width="500" height="500"> syntax.
Everything is working well except with Apple Devices (Default MAIL App and Outlook for iOS) where the Embedded images are displayed as Empty Boxes.
------------------------------------------------------------------------------------------------------------------------------------
While I'm still working on this automation, the process is currently performed manually by doing the following:
- Compose the Email using Outlook Desktop
- Insert an image as embedded or inline in the Email's body
- Send the email
By doing the manual email steps above, all of our Users INCLUDING APPLE DEVICES can view the embedded image properly. I investigated this and retrieved the HTML codes generated by Outlook Desktop (More Move Actions> Other Actions > View Source) and proved that Outlook is using CID as Image Source but instead of using only the file name it seems like the format is <attachmentFilename>@<attachmentContentId>. I can't replicate this syntax for I don't know where to get the Attachment Content ID.
Additional Info:
- Recipients of the email are using different devices such as Outlook Desktop-Android-Apple, Outlook Web App, Samsung's Built-in Mail App. Source: CID has been tested and works with all of these devices except for Apple.
- Using Base64 as image source is not possible since this has more issues in other devices especially with Outlook for Desktop
- Using Publicly Available links (Azure Blob) are not allowed in my Organization due to the Image's confidentiality, additionally, it doesn't seem like a secure standard way of embedding email in a professional environment.
