Mailto links do not work on my mac

Question

After checking this question (Mailto links do nothing in Chrome but work in Firefox?), I have tried & determined:

• I originally had this setting (Chrome Settings->Content Settings->Manage Handlers... (chrome://settings/handlers)) set for email and calendar links to use the associated Google Service I have an account for, assuming they will try to access the service through the Chrome browser.
• I removed my existing handlers. Clicking the mailto link still does not work, and I am not able to add one manually through Chrome.
• I do not see a relevant setting in Microsoft Outlook for Mac 15.33 to utilize.
• I was not able to readily reset this behavior to investigate further, as going to Gmail does not reveal the handler icon again:

• I experience this problem in both Chrome and Firefox.
• I have tried links without a target attribute, and with one specified to "_top", _parent", and "_blank". (mailto link is blocked as insecure content in Chrome Gmail.)

Mac 10.12.3

Solution 1

Open Mac Mail and Preferences Dialog. Ensure you have Default email reader set to Mail.app (or whatever app you use for mail).

Solution 2

Followed these steps and worked very nicely:

• Run the Mail application.
• On the Mail menu, click Preferences.
• Click the General tab.
• For Default email reader, select Microsoft Outlook (or what you like).
