When you type or paste a web link into Office, it normally converts it into a web link automatically. But occasionally that feature doesn’t work right.
We found one example when researching the famous artist Roy Lichtenstein and one of his best known works.

And that Wikipedia page is how we found the Office bug. The name of the painting, and therefore the web link, has an exclamation mark. If you paste that link into Office, it ignores the exclamation mark as part of the link.
The result is a web link that doesn’t work because it’s incomplete.
It’s a small thing but something to watch out for. Office doesn’t always properly convert text into a clickable link.
