Question

Hey Guys,
I'm experiencing an odd issue with Office.
Whenever I try to open a hyperlink in PowerPoint, Word, or any Office Application I get this error.

Event Viewer shows this.
- <Event xmlns="**http://schemas.microsoft.com/win/2004/08/events/event**"\>
- <System>
<Provider Name="Microsoft Office 16 Alerts" />

</Event>
Has anyone experienced this issue and have any idea how to resolve it?
Any help is greatly appreciated.
Also to add, if I change the default browser to Edge or IE the hyperlinks open fine. It's just Google Chrome which causes this issue.
I've tried updating Chrome, updating Office, and updating Windows to no avail.

Finally found the issue, Windows Defender Exploit Guard was blocking it. Found it in the Event Viewer > Windows Defender > Operational

Hi,
I suggest you refer to this support article, it seems that Chrome breaks the association for http file type:
https://www.ablebits.com/office-addins-blog/2014/01/16/hyperlinks-not-working-outlook/
As the article said:
"The main reason of hyperlinks not working in Outlook is the default Internet browser not registered (properly) in your operating system. Typically, this issue comes up after uninstalling Google Chrome or changing the default browser from Internet Explorer to either Chrome or Firefox.
Mind you, the default browser might be changed even without your notice by some misbehaving add-in or application that installs Chrome / Firefox along with its own files and makes it the default Internet browser unless you remove the tick from the corresponding checkbox. And naturally, that option is not very noticeable, so anyone can easily overlook it during installation. An evident example of such programs is Adobe Flash Player that may install Chrome both during the first installation and updates, so be sure to uncheck that option on the next update to avoid the problem with hyperlinks in your Outlook.
Well, this is the most typical cause, though Outlook links may stop working in some other scenarios and even without any obvious reason at all. Okay, know that you know the cause and consequences, let's see how you can get the problem resolved."
Hope it's helpful.

Hi Emi,
I still haven't been able to get it resolved. It works with Edge and IE but not chrome.
I've tried plenty of different registry settings to no avail.
