Have you guys ever faced an issue when you try to add a online Shared mailbox to SharePoint workflow? I am not sure even if this feature is available or not? Can anyone know if Microsoft is allowing SharePoint online workflow to send email to "Shared Mailbox"?

Note: All our online Shared mailboxes are in block stage. Is this because of that they not showing up while adding them to "SharePoint workflow" . Is there any alternative to add them to workflow without even unblocking them?

If the shared mailbox isn't working when you choose it from the global address list; instead you can store the shared mailbox email address as a variable within the workflow, then have the email sent to that variable. Screenshots to support answer

The problem is that cannot enumerate the mailbox as a SharePoint user. To get around this, you can add the mailbox to the members group of a site and magically the workflow will send email to that address.

Or alternatively, you can trigger SP Workflow 2010 from SP WF 2013 to send the email to Shared Mail.

  • Thanks for your response. I will add shared mailbox in a group and will give a quick try if it works or not Commented May 15, 2018 at 15:31
