How to send email as 'Send on Behalf'

Hi ​@vdhomane ,

You won’t be able to achieve this using the Outlook package in A360.

Even if you:

• Connect to the shared mailbox

• Select the shared mailbox folder

the Send Email action always uses the “default Outlook profile account”. There is no option in the Designer to set “Send As” or “Send on Behalf” in Outlook commands  so what you’re seeing is expected behavior.

What you can do instead

Option 1 - Use Email: Exchange / Microsoft 365

Switch from Outlook package to Email package (Exchange / M365).

• Use Email: Connect (Exchange or Microsoft 365)

• Authenticate using a user who has:

  • Send As OR

  • Send on Behalf permission on the shared mailbox

• Then use Email: Send

In this setup, the email will go from the shared mailbox (based on permissions and connection used).

Option 2 - Use SMTP

You can also use Email: Send (SMTP)

• Configure SMTP (e.g. Office 365)

• Provide credentials of a user who has access to the shared mailbox

• Set From address = shared mailbox email

This works if the mailbox permissions are correctly configured.

Key point

Outlook package in A360 is tied to the local Outlook profile, so it does not support overriding the sender address.

Before implementing, confirm:

• Do you need Send As or Send on Behalf?

• Do you have permission on the shared mailbox?

• Can you switch from Outlook package to Exchange/SMTP?

If you’re restricted to Outlook package only, then there’s no direct way to achieve this in A360.

Outlook 365 send & SMTP Send

Let me know if this works for you
