Are you having trouble with links in Microsoft Outlook? Do not worry as I have seen this many times and have many solutions to get you up and running in a few minutes.
Google Chrome Browser
The Chrome browser by Google is one of many free Internet browsers that can be installed on your Windows PC and If you make it the default browser and later remove it from the system without making Internet Explorer the default browser once more, this will cause issues with links in Microsoft Outlook. So why does it happen? The issues happens as Outlook is still trying to open your links with the Chrome browser which is no longer installed.
Using one of your installed free Internet browsers, navigate to the Outlook Web Access URL (ie. http://mail.example.com) that is used for remote email access and try to login. Once in, look for the email and try to open the link that would not open. You should be able to open the link now unless the Firewall or Antivirus Software sees it as rogue.
To fix your issue temporarily, you will have to go through the process of reinstalling Google Chrome to open your links.
Microsoft Outlook and Microsoft Windows will need updates which includes a manual downlaod patch that is already available by Microsoft for Outlook 2010, 2013, and 2016 versions to limit it from happening again. You can then remove Google Chrome if you had it reinstalled and no longer require that browser.
