To set up your Google Workspace email (formerly G suites email) first you will need to enable the NowCerts webmail app. I will put detailed instructions below.
login to the admin of your Google workspace at admin.google.com
Click on security either from the left-hand menu or on your home screen.
Select API controls.
Select Manage Third-Party App access.
Select OAuth App Name or Client ID.
Type in the NowCerts App ID: 65080291429-05l4mdhkgm9dacle772sq5r1r5o0aepk.apps.googleusercontent.com
Click the check box and then select.
Once this is selected and added as a trusted app you can now sync your WorkSpace emails into the NowCerts webmail platform.
