Hi Ayal,
Do you mean you are attempting to configure a Gmail account on your Outlook? If so, since our forum focuses on Office 365 cloud related services, we have little resource about configuring none-Office 365 accounts to Outlook clients. To ensure you get dedicated support, it is recommend you post a thread in Outlook client forum via the following links:

Thanks for your understanding.
