Links in Outlook Emails cannot be opened, error message

[Droppy4]

Using Windows 10 Version 1903 Built 18362.356, Microsoft Outlook 2010 (14.0.7236.5000) SP2 MSO (14.0.7237.500) and Google Chrome (Version 77.0.3865.90) as Standard-Browser.

A Registry clean with CCleaner Free v5.61.7392 (64bit) result in a deleted Registry Key

"C:\Program Files\Internet Explorer\IEXPLORE.EXE" %1    HKCR\htmlfile\shell\open

what cause this problem

Hyperlinks are not working in Outlook

I could resove the problem with Method 3: Export and import the registry key from another computer

 

It would be great if you leave this key untouched with the next realease.

This is less a bug and more a misunderstanding of how reg cleaning should be done.  It sounds like you just trusted ccleaner to be 100% right on every entry it finds.  It's much better to look at every entry individually which ccleaner gives you the chance to do.  You should follow the advice in my signature below this post for good rules to follow when using the registry section.
