Update MailMessage subject on Exchange Server?

Hi all,

Is there a way to update a mail message subject line after the message has been fetched from a Get Exchange Mail Messages activity?

I can fetch messages, and then iterate through each message and do a simple

item.Subject = "New subject"

However, I can’t find a way to save/update that change back to the Exchange server.
Any ideas? Thanks! :slight_smile:

Hi @Adam_KellingrayWilliamson,

If an email is obtained from Get Exchange Mail Messages activity that means it must have been sent already. Once an email is sent , there is no way to change it on the Server. If this was possible no one would trust an email in a formal context !

Hope that helps !

Thanks & Regards,


You can change the subject line on emails received though through the Outlook application… Which is all I’m trying to replicate (just not through the UI)
