Convert email to pdf

(0) ShareShare
ReportReport
Posted on by

Basically I have a very simple workflow that is supposed to be triggered by when I receiver a certain e-mail in my outlook, that then converts the e-mail to a PDF and updates it to a sharepoint file library.

 

I have done this workflow before with other e-mails and it has worked fine. Attached are screen shots. I have tried two things one where I specify the file’s extension as .html and another one as a .eml. Both yield errors.

 

When I specify HTML the workflow runs for a while. And then gives me this error:  Error 502 Gateway:

    }

  }

}

 

 

When I specify it as a .eml it errors at the same step with a different error:  Conversion of this file to PDF is not supported. (Sandbox_BadArgument_Argument / Invalid destination page in call to CreateDocumentLink: page number is one-based and must be 1 or higher.)

    Hi @SharePointNinja ,

     

    You shouldn't need the compose step above, and you can use .msg as the file extension. This test flow seemed to do the trick for me:

    Hi @SharePointNinja ,

     

    Please refer to below thread:

    https://powerusers.microsoft.com/t5/Building-Flows/save-email-as-pdf/td-p/109005

     

    In addition, the compose action is not necessary in your case, you may try change the file name from the output of compose to a fixed value such as the Email subject, and check if it is the output of compose caused the problems.

     

    Hope this helps.
