When you first login to your Williams Gmail account in Chrome, you’ll see a double-diamond icon in your address bar on the right-hand side. Clicking this icon opens a menu asking if you'd like to allow mail.google.com to open all email links. Choose Allow. Chrome will now open a new compose window whenever you click on an email link.
If you don’t see the double-diamond icon in your Address bar, you can reconfigure the email handler in your Google Chrome settings:
- Go to Chrome > Settings > Privacy & security > Site settings
- On the Site settings page, under Permissions, select the drop down to the right of Additional Permissions, then select Protocol handlers
- First check that Sites can ask to handle protocols has been selected.
- It's likely that mail.google.com has been listed under Not allowed to handle protocols. Click the X to the right of it to remove it from the list, then open Gmail in a new tab, or refresh the tab it's currently opened in, to have the double-diamond icon reappear.
You can also access these settings by right clicking an email link and select Open Link with. If you see mail.google.com as an option, select it to open a new compose window, or choose Configure and remove the current default if it's not mail.google.com. Once the default is removed, the double-diamond icon should appear in the address bar when you refresh or open up a Gmail tab.
