Send Exchange Mail with Shared Mailbox

Hi,
I try to use SendExhangeMail activity with a user who is connected to a shared mailbox. It keeps giving the following:
“Send Exchange Mail Message: No mailbox with such guid.”

I put the following setting:

  • EmailAutodiscover: [sharedmailbox@email.com]
  • User: [user connected to the shared mailbox]
  • SaveCopy: [ticked]
  • From: “sharedmailbox@email.com

Fyi, I am able to use Get Exchange Mail for getting email from:
MailFolder: “Inbox”
SharedMailbox: [sharedmailbox@email.com]

Anyone can help me or had a similar experience previously?

Thanks,
Phx

@phoenixavatar,

Welcome back to our community!.

This error is commonly caused by an unlicensed mailbox account. Check that all of the migrating mailboxes are licensed in Office 365 first.

If a mailbox account has been assigned a license and the error persists, it is usually caused by a non-Null value in the “msExchMailboxGuid” attribute of the mailbox account.
