Solution #2. Reset URL File Types When Links Not Opening in Outlook

If you've made it this far, your Outlook hyperlinks are still not opening. But don't worry, we've got another solution to try. It seems like somewhere along the way, your file associations might have gotten messed up. These associations are what Windows uses to link a file type to a specific program. In this case, we need to check the HTTP protocol mappings.

To check HTTP file associations:

Step 1: Press the Windows key + i to open your Settings panel. In the "Find a setting" box, type "protocol."

Step 2: From the search results, select "Choose a default app". It might take a while for this page to load.

Step 3: Scroll down to find HTTP and HTTPS under "Choose default apps by protocol."

Step 4: Make sure Microsoft Edge is set as your app. Close both Edge and Outlook and test your Outlook hyperlink again.

Solution #3. Choose Microsoft Edge as Your Default Web Browser

Some users often resolve my Outlook hyperlink issue by resetting Microsoft Edge as their default browser. Moreover, they typically recommend switching to Microsoft Edge if you contact Microsoft for assistance.

To make Microsoft Edge your default browser, follow these steps:

Step 1: Open Microsoft Edge. In the address box of the browser, type "edge://settings/defaultBrowser".

Step 2: Click on the "Make default" button located at the top.

Step 3: Close both the Settings tab and Microsoft Edge.

Here's how to reset settings in Microsoft Edge:

Step 1: Open Microsoft Edge. Type "edge://settings/reset."

Step 2: Select "Restore settings to their default values" from the "Reset settings" menu.

Step 3: In the Reset settings dialog box, click the "Reset" button.

Another potential solution, although less common, involves re-registering certain DLL files. While this might sound complicated, it's quite simple. Depending on your Outlook version, there are six files to register. Some configurations utilize shdocvw.dll, while others utilize shdoc401.dll.

Here's how to re-register the DLL files:

Step 1: Close Microsoft Outlook. Press the Windows key + R.

Step 2: In the "Open:" textbox, type "regsvr32," followed by a space and the file name.

Step 3: Click the OK button. You should see a message indicating the process succeeded.

Step 4: Hit OK to dismiss the message.

Step 5: Repeat the procedure for the other DLL files.

  • regsvr32 Oleaut32.dll
  • regsvr32 Actxprxy.dll
  • regsvr32 Mshtml.dll
  • regsvr32 Urlmon.dll
  • regsvr32 Shell32.dll

Once done, test to see if your Microsoft Outlook hyperlink problem has been resolved.

Solution #6. Verify HTML Registry Key Values

This solution involves accessing the Windows Registry, which may seem daunting for some users. Sometimes, registry values can be reset by other programs or become corrupted. As a precautionary measure, it's advisable to always create a backup of your registry before making any changes. If you're unfamiliar with navigating the registry, it's a good idea to seek assistance from someone experienced in this area.

Here's how to access the Windows Registry and make the necessary changes:

Step 1: Press the Windows key + R to open the Run dialog.

Step 2: Type "regedit" in the text box and click OK.


Step 3: Click Yes on the dialog asking if you want Windows Registry to make changes.

Step 4: In the left pane of the Registry Editor, navigate to HKEY_CLASSES_ROOT.

Step 5: Scroll down until you find ".html" in the menu. Click on the entry. Your top bar should display "Computer\HKEY_CLASSES_ROOT.html."
