Helping people with computers... one answer at a time.
The list of BCCed recipients is not included in emails, so there is no way of determining if and who else the email was sent to.
I want find the list of "undisclosed recipients" of the email I've received in Outlook. Is there any way?
•
"Undisclosed recipients" is often placed in the "To:" line by some mailers when the email being sent has no entries in the "To:" or "Cc:" lines. The sender has used the "Bcc:" feature of email to send the email to one or more people, without revealing who they are.
So, how do you find out who they are?

You don't.
That's what "undisclosed" means. The information about who the email was sent to is not included in the email. There is simply no way of determining if it was sent to anyone else and if so, who.
Now, to be complete, I do recall hearing about some old email programs – and we're talking ten or twenty years ago – that got the whole concept of Bcc: and undisclosed recipients wrong. They included the BCCed recipients in headers that everyone could read if they knew how. But that was a serious bug and has long since been resolved.
Today's email programs simply don't disclose undisclosed recipients.
It would be wrong to do so.

When searching for a surname in Outlook Inbox emails appear in the search results but there is no mention of that particular surname anywhere within the email. Is this potentially pulling out surnames of recipientss that we BCC'd?

Leo, if an e-mail was sent to me and someone was Bcc’d in it and I reply to all, the person that was Bcc’d will also see my reply. How is this possible if your statement, “The information about who the email was sent to is not included in the e-mail”, is true? The only way I can see that the Bcc’d person will get my reply is if his details are somewhere in the incoming e-mail that I'm replying to.

If you reply to all in an email with BCC, the people on the BCC list shouldn't get a copy, as their name and address info doesn't appear on the emails sent. I can only imagine that happening if there were some bug in the email sending program or website. I would say the same for the case where the BCC list appears momentarily on the iPad. BCC is not supposed to transmit any receivers' information to any of the other receivers.

I was under the same impression as you, but this is what happened that made me post a comment:
One of my suppliers sent me an e-mail and Cc'd someone else in her organisation, so I automatically "Replied to All" with my response. Just after that I received and "Out of Office" from her manager, but he wasn't addressed in the e-mail as far as I could see, so the only way I could have received an "Out of Office" from him was if he was Bcc'd in the original e-mail that I replied to.

Leo concerning your sabbatical observance are you getting paid to read comments if not how is that violating the law? Jesus performed miracles and help people in need even on the 7th day, Saturday.
