Until 3 days ago I hade no issues with using hyperlinks in my Outlook 2021. Now when i select a hyperlink, I get this error message.

"This operation has been cancelled due to restrictions in effect on this computer. Please contact your administrator". I am the administrator.

I have also tried everything I can think of to check where the issue is. I have also noticed that the security zones in internet properties are completely greyed out with no option to change them.

I can send and receive enails via Gmail, no problem, its just when i select a hyperlink. Internet Greyed Out

Hi @Allan Bower

Thank you for reaching out to Microsoft Q&A forum.

First, make sure you are logged in as admin account. To check this, go to Settings > Accounts > Your info. If your account has Administrator privileges, it will say Administrator under your username.

Or you can simply right-click any app (e.g., Notepad) > Run as administrator > If you only see a Yes/No prompt, you’re an admin. If it asks for an admin password, you’re not logging in your admin account.

For Outlook link issue, kindly try the steps below and see if this helps.

  1. Reset Internet Options settings for (Windows 11)
    Go to Control panel > search for Internet Options > Advanced > Restore advanced settings.
  2. On a computer that does not encounter this problem, select Start > Run. In the Open box, type regedit, and then select OK. Locate, and then select the registry subkey: HKEY_LOCAL_MACHINE\Software\Classes\htmlfile\shell\open\command. On the File or Registry menu (depending on your operating system), select Export. Note the location where the file will be saved. Type a unique file name, and then select Save. Exit Registry Editor. Copy the exported registry key to the desktop on the problem computer. Double-click the .reg file. Select Yes > OK.
  3. Verify that the String (Default) value of the HKEY_CLASSES_ROOT .html key is htmlfile.
    Press Windows + R > Type in regedit > locate the path.

All the methods above require admin privileges to perform.

Please try and let me know if it works for you. I hope this information helps.

    Hi @Allan Bower

    If you are using Edge, you can try resetting default browser associations in Settings → Apps → Default Apps for HTTP, HTTPS, html, htm.

    Apologies I posted the wrong screen save.

    The html default key shows as HTML Document. I have edited it to read html

    Hi Jayden

    Thanks for your reply.

    Unfortunately your suggestion did not work. I think I followed your instructions correctly, but on the affected desktop, the regedit window is different to my un-affected laptop. If I follow your suggested route to the html file, there is no command line. I have to go to edit to find a command line
