Hi, I'm Robert and I'll be helping you with your computer question.
I am stuck on where google says you can't use outlook ?
i use outlook for gmail all the time.
No but you might misunderstand something like googles security procedures which require you to set gmail to allow it to be used by pop or imap in another program
it just took me about 5 seconds to add a gmail account to outlook
there is something set wrong in your gmail account and thunderbird will have the same problem
i just added a gmail account to apple mail for somebody yesterday and it had no problems
set it for imap it should be using the same password ***** the incoming
you might have the wrong port or ssl settings. but it will work better under imap than pop
these are the proper settings
