Email Message - Set "From"

I'm sending automated emails using the Office 365 Outlook "Send an email (V2)" action. That works fine. What I also want to do is record that I sent the email on the Case. I'm using the CDS "Create a Record" action and setting the Entity Name to "Email Messages".  The "From" box says "Sender of the email.", but no matter what I try, the "Sender" field in the Output is always null. 


Here is what I've tried that has not worked:

  • Text - ""
  • My user GUID 
  • systemuser(my user GUID)
  • /systemuser(my user GUID)
  • mailbox(my mailbox GUID)
  • /mailbox(my mailbox GUID)
  • Get the email from Office 365 Outlook "Get Emails (V3)" action and passing the "From" field. (Description says "The mailbox owner and sender of the message.")


I've found a few posts from 2019 that show being able to set the Activity Party, but the Action no longer offers me that option.


Anyone know the secret to populating the From field? (The To field is giving me the same problems, but it's not as much of a concern to me.) There seems to be no documentation (that I can find) on the Email Message entity.

Hello @Spamrancher 

Have you tried to use Contacts(your user GUID) ?


Hope it helps!

Hi @Spamrancher,


I tried on my side to insert a value into the From field when creating a CDS record, but it did not work either.

As a workaround, you could create a custom Email field named EmailFrom, then try it again, for example:

Thanks for the suggestion, but that still doesn't solve my problem of "Email from" not showing any information. Is this something that should be reported as a bug?

Thanks for the suggestion. When I tried that it couldn't find a Contact with my System User GUID, which I suppose is not surprising.
