gControl gMail Block Settings

Corporate Google apps emails use the same URLs as the consumer Gmail. Hence it becomes difficult for the administrators to block the consumer gMail for the users. With gControl’s Gmail block setting administrators can achieve this.

Gmail block is a chrome extension built by Cloudcodes. Hence for this feature to work, user should be accessing the emails via chrome browser and they should have this extension applied on the browser. gControl provides 2 ways of applying extension. To manage the way extension gets applied, administrator can log into gControl control panel and select the “Setting” option from the quick links on right. In preference settings go to “Extension Setting” tab.


You will have 2 options.

  • User Managed: This is the default option. In Case of user managed user needs to install the extension himself. If the user in Gmail Block policy tries to login, he will not be allowed to log in until the user installs the extension. He will get a prompt in the login page to install extension and a link which will take him to the web store from where he can apply the extension on the browser.

  • Admin Managed: Admin can push the extension to users chrome browser. The instructions to push the extension are shown when the administrator selects the admin managed option as shown below

Note: For admin managed extension to take effect, the end user has to log into chrome at least once.
