I noticed a while ago that when I clicked the email icon or link on a website that it was just opening to a blank page instead of opening my email client, like it used to. I ignored it for a while but finally figured it was time to fix it. Then I found this great article that shows just how to do it:
When someone does a great job with a tutorial, I don’t feel the need to redo it. Here are the highlights, but be sure to check out the actual article for step by step instructions along with screenshots.
Set Gmail as Default Email Client on Windows 10
First, open your Chrome Browser head to Settings > Advanced > Privacy and Security > Site Settings > Handlers.
Now make sure the switch for Allow sites to ask to become default handlers for protocols (recommended) is turned on.
Next, sign in to your Gmail account and click the handler icon next to the star icon on the right side of the address bar (shown below). And choose Allow from the dialog box and then click the Done button.
Then, just like with changing other default apps in Windows 10, head to Windows Settings > Apps > Default Apps > Email. Change the Email app to Google Chrome in the right panel.
