HTML image in send email from shared mailbox

Posted on by lmheimendinger 260

I have chased this down a variety of rabbit holes but no luck.  A quick summary,

 

When I started testing, the email I sent to myself worked great because, I now believe, <img src"...> was a local file on my computer.  Soon discovered that other recipients not only could not see it but couldn't download it either.  

 

I then saved it to a company OneDrive and grabbed the shared link, but then I couldn't see it nor download it in my email either.

 

I then tried converting it to base64, saving that as a text file on the company OneDrive.  Then several things after that which also didn't work, either Power Automate initialize errors or image errors when viewing in Outlook.

 

Fairly certain that getting this to work is just a few steps away from where I am, but not sure what they are.  Greatly appreciate any help.  I thought there was a file convert to base64 function in Power Automate but couldn't find it.

    Hi @lmheimendinger ,

     

    I agree, you are probably very close to resolving this issue.  Have you tried?

     

    dataUri(body('Get_file_content_using_path'))

     

    how to add company logo in email body - Power Platform Community (microsoft.com)

     

    Let me know if this doesn't work - it looks good to me.  I am also going to test it out tonight too.

    I did try this but got this error

     

    Unable to process template language expressions in action 'Send_an_email_from_a_shared_mailbox_(V2)_2' inputs at line '0' and column '0': 'The template function 'dataUribody' is not defined or not valid.'.

     

    In email body I had this HTML code

     

    <img src="@{dataUribody('Get_file_content_using_path')}" > </img>

     

    My expression mimicing the article was 

    dataUribody('Get_file_content_using_path')
     
    So no it didn't work for me

    Hi @lmheimendinger ,

     

    Yeah, I tested this and got an error too!  Ok, I was successful with an image from both OneDrive and SharePoint; but not 100% sure this works for external users?!?  I could not get the image to appear in gmail but some progress - could just be a sharing issue.

    The left side is OneDrive; right is SharePoint.

    I tried duplicating your OneDrive steps but at first the dynamic content from the Get File Content using path didn't show up.  I got around that by changing advanced options from Yes to No, then did trhe compose step and send email step.  When I ran it got a similar error as before

     

    Unable to process template language expressions in action 'Compose' inputs at line '0' and column '0': 'The template function 'dataUribody' is not defined or not valid.'.

     

    I changed the No option back to Yes and re-ran but same error occurred.  The flow never gets to the send email step.

     

    The file I am using in OneDrive is a .jpg not a .png.  Might that make a difference?

    Hi @lmheimendinger ,

     

    No, the file type png vs jpg won't make a difference.  Based on the error message, review the format, you could be missing a parenthesis.

    dataUri(body('Get_file_content_using_path_2'))  // in my example for OneDrive, double check the bold text here
