I couldn't find any of the settings, using the latest version of outlook..
What is the email server? Gmail? Outlook.com? O365? GSuite? ZoHo? You have to know this.
I don't have that information.. and I have no way of finding that out..
Well shit.
If you ever received an email from this person, you already have that information.
is that right?
can you explain what you mean, please ?
Take the email you received and look for "Show Original" or something similar in your mail client.
It will show all the headers and information that the mail servers have sent between them. There you can see what provider someone is using. Often also what mail client.
this?
spf=pass (google.com: domainBoth the sending side and the receiving side puts information in the email headers.
There is no context to the little snippet from the headers you posted so I can't determine where google is in the chain.
Search for "email headers" on the net and you'll find more info on how to interpret it.

So I told him to reach out to his Email Admin and have them make the required changes in outlook..
Outlook is a desktop client. Seems unlikely their email admin would have access. Their desktop admin would normally do it.

I'm wanting to learn about how to fix email for future reference. . . please be nice.
I've never touched email outside of being a user.This kind of stuff depends heavily on what the email server is and then what protocol was used to connect to the email server from Outlook (since that is what you said they have)
My understanding is they are using IMAP to connect to the Server through outlook.
IMAP is a mailbox protocol, not an email protocol. You can't send email using IMAP or POP. You can only send using SMTP (email = SMTP.)
They likely use IMAP, but that's to read the contents of their mailbox not to send or receive email. Complicated, yes, but mostly only because people call files already received over email email when they are really just text files on their file server. Hence why a file server management protocol like IMAP is often incorrectly called the email protocol.
But SMTP is always what sends and receives email.

That may be true to RECEIVE email. But is useless for sending.
IMAP is only for receiving email.
Not even for receiving. For READING after it has been received. Semantics, to some degree, but very important semantics. In a modern email system SMTP is the only protocol used. IMAP and POP are only in play when you deal with legacy mailbox clients (Outlook, Thunderbird, etc.) If you don't use those clients, you still receive your mail just the same, but never have IMAP anywhere.

The rest of us understand that.
The rest of us also understand that you are not talking about the email server for sending and receiving and we are not trying to confuse you by bringing in more information than you can understand.

You're not just looking for one string. You need to look at the whole thing.
I suggest you copy the headers from the start until you reach the line starting with
From:
Paste it into this page: https://mxtoolbox.com/EmailHeaders.aspxIt should tell you what servers are in use for sending and receiving.

What version of Windows and What version of Outlook?
Windows 10
I didn't look - we dont support email so this is mostly just a way of wondering what I should be looking for in the future.

The top one is the last transfer. There's missing "from" but judging from the IPv6 address this is likely internal google mail server to google mail server.
