Microsoft Outlook started displaying the following error message when clicking on links within emails on one of my PCs.
“This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.”
So I get “contacted” but have no idea why it’s doing that! So a Bing search later and I find a registry fix.
It has something to do with Google Chrome being uninstalled from a PC and it doesn’t set the links back to the right defaults.
The following instructions (found here) fixed the issue for me:
If you received this error after uninstalling any application that takes over the HTML open command (including, but not limited to, Chrome & Firefox browsers) you may also need to change the HTM/HTML association in the registry.
- Start, click Run, type Regedit in the Open box, and then click OK.
- Browse to HKEY_CURRENT_USER\Software\Classes\.html
- Right click the value for the .html key and select Modify…
- Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
- Repeat for .htm, shtml, .xht, .xhtml, .xhtm keys
