Outlook digital signature impacting Sharepoint List workflow

(0) ShareShare
ReportReport
Posted on by 4

I have created a list in Sharepoint that pulls Outlook emails. I have it set to pull various email components such as sender, recipient, email body, email attachments, etc. Currently, I am having an issue with digital signatures. If an email has a signature, my workflow will not recognize any additional attachments. 

A successful attachment pull occurs when an email does not have a digital signature:

The same workflow with the same email attachment fails when an email has a digital signature. This smime.p7m attachment is identical for a variety of senders, leading me to believe this is a file representing the digital signature.

I tried to set a condition to ignore this file type. The workflow is set as follows:

This was successful in ignoring that signature; however, the other email attachments were still not loaded.

 

Is there a way to set the workflow to ignore (or incorporate) the digital signature and any attachments??

    Hi,
     
    You may try 'Is Inline' property to check for email signature. This will be true when an image is embedded in the email body:
    Pls note that you need to enter true as expression in 'Function' window.
     
     
     
    If this helps & solves your problem, please remember to like and accept my solution as it will help others in the future.

    Hi, 
     
    Thank you for the suggestion. I implemented it, but unfortunately, this does not solve my problem. I only get the 'smime.p7m' attachment in my sharepoint list.
     
    I don't believe it is the embedded email signature that is causing the issue. I believe it is the digital signature/certificate that is assigned to the email address??
