Problem adding GMail Account to Outlook MS-Office 365

This threw me for a loop this morning for a couple of hours. I logged in via the web browser just fine. I set my GMail account for IMAP. Still couldn't add it to Outlook.
Kept getting this error message despite several attempts and triple-checking my spelling, etc.

Your IMAP server wants to alert you to the following: Please log in via your web browser:

Cause

This issue occurs when you try to sync to a Gmail account after July 15, 2014 and Basic Authentication has not been enabled for your Gmail account.

Google has increased its security measures to block access to Google accounts after July 15, 2014 if those accounts are being set up or synced in apps and on devices that use Basic Authentication.

Resolution

To resolve this problem, enable Basic Authentication for your Gmail account. To do this, go to the following Google website, and then select Enable when you are prompted about whether to let less secure apps access your Gmail account:

Allow less secure apps

For additional security, consider enabling Google’s two-step verification and app passwords as documented at the following web pages:
