smtp issues and an auto-filled password that I can't change

So I am trying to set up the scan to email function on my organization H625cdw dell printer.  I have been following the recommendations in the printer manual (page 241 and 242) and on posts such as the links below.

I have yet to succeed.  I have tried it on gmail and outlook accounts and failed on both  These are the settings I have entered in so far.  I'll use my outlook account settings as an example. 

In the process of doing this, I think I have discovered what is wrong.  But I don't know how to fix it.  I can't seem to change my smtp login password.  The password is autofilled with 4 letters (hidden of course) and I can't seem to override it.  As you can see in the pic above, this 4 letter password is also autofilled into the POP section.  It's also autofilled into the administrator password section.  I believe that I am supposed to put the password of the outlook account into that password area.  But I can't get that password to save.  I'm stuck with this unknown 4 character password for some reason.  Whenever I try to scan something with this, I get the 016-764 failed to connect to smtp server error, which makes sense because I can't put in the right password for the email account. 

1.  What can I do to actually change that password?

2. Does it matter which email goes into the reply email section?  Right now I just have it as the first email in the printer address book, which is my work email.

3. Do you see anything else that would be a potential cause for not being able to connect via smtp?

Any advice is appreciated.  Thanks in advance!
