SO they're running Postfix as a mail server?
Yes, which most people do. Postfix powers the vast majority of non-Exchange email. It's the big leader.
Okay great ..
@JaredBusch They're running Postfix mail Server on outlook.
Outlook is an email client. It runs on your desktop. It's not a server or anything like that. Nothing runs "on it."
This entire discussion is about Outlook.
I know, about what Outlook is talking to. Postfix (nor any other email server) does not run on Outlook.

We have a customer who is using a host firewall
FYI, it is an assumption that every computer has a host firewall. While some crazy people turn it off, it's not a special case.
By default, host firewalls (and regular firewalls) don't block outbound traffic.

what I mean by "hosted firewall" is we have our vendor's security team manage the firewall on the network. . .
meaning that we do not have access to it other than to the physical box it's self. -

I've never touched email outside of being a user.
That's all that is likely going on here, user side settings are probably wrong. We don't have enough details to know for sure, but most likely that is all that this is. This isn't an email admin or admin thing at all, we suspect, just an MS Office configuration.
You should play with some email systems as an end user to see how they interact. Using Thunderbird and Outlook will give you a lot of exposure. Connect them to a couple different systems like O365 and Gmail and a more basic service to see what end users experience and how all of the configuration is for the end user.
Would also be recommended to run your own email server. That'll teach you a lot really quickly.

So would it likely to assume that Username and password are incorrect ?
If the computer receives email, then the username and password were likely correct. Outlook's account setup wizard will only ask for the information one time by default.
If this system has never been able to send email, what is likely incorrect is the email server configuration details.
If it once sent email, then mostlikely Outlook had a connection problem once and popped up the credentials box, then the user put in the wrong info.

A hosted firewall lives elsewhere, at someone else's datacenter. Because that's the "hosted" part of it. Hosted firewalls are pretty useless in general, you have to VPN to them from behind your own firewall and it's just a lot of latency.
Managed firewalls are standard, we manage firewalls for every customer. You can test email like any other connection to see that the firewall is or isn't a problem. Just use your telnet as it is a TCP connection and that will tell you what is going on.

you mentioned three locations before - is this person using a laptop and traveling between these locations?
You also mentioned that it worked at the other locations just not at this one location - is that still accurate? -

3 locations - all similar hardware setup -
Back office Manager PC, Server, Rack and hosted firewall.He has 3 different email accounts setup - 1 for each restaurant location .
he travels with a laptop and can't send emails from this 1 location neither on his laptop over Wifi , nor on the Manager PC.

Ah, if it is location based, that certainly sounds like the firewall managers have gotten heavy handed and decided that email apps like Outlook are going to be blocked at a network level.

Was on the phone with the firewall admin team yesterday, and they showed that emails were leaving the site through the firewall ....

Can you do the standard networking test with telnet? That will tell you more than anything.
That "emails" are leaving the site is not at all the same as "his emails are leaving the site." It's pretty standard to have email locked to a single port from a single machine. So that they showed you that working and not what you asked about, is telling on its own.
