Windows 7: Outlook suddenly giving "operation cancelled"

Hi y'all. I run plain-vanilla Windows-7 on a new Dell desktop, at home. I use Outlook for mail (wife's suggestion) and it worked normally for a month. But recently when I click on a link in an email, program displays,
"This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."



This seems to be a genuine Windows msg, not a virus.

Tried looking thru Outlook's Help but...nothing. Now I'm wondering if perhaps I inadvertently changed a setting on the OS itself, which is what I'm checking here.

Anybody ever seen the message noted above? Ideas on what it means and how to fix? Many thanks.

Hiya and welcome to the forums.

Have a looky here pal You receive an error message when you click a hyperlink in Outlook

Thanks--that's the culprit all right. However, the auto-fix said "failed to correct" or similar. I'll run thru the manual fix and see if that does it.

As an aside, I use Firefox as my default browser, and I see the Microsoft fix is geared to making IE the default. That strikes me as a likely snafu.
But again, your brain saved me quite a few hours of search time, so many thanks!
