unable to add gmail to outlook mac client (old look)

hello I have been trying to add my gmail account to my mac outlook client.

I click add account, 

asked me to add my email address

I enter my gmail account

sends me to my browser to authenticate in google and allow permission, when accepted

sends me back to outlook but outlook remains on the same screen

No options. nothing to do..... I believe is due to microsft cloud sync but I cannot disable it.  

Any ideas or work arounds would be great
