Has anyone configured Onedrive known folder redirection\sync for the 'desktop' folder on environments where Citrix Workspace places pub app/desktop shortcuts in that same folder? Reading some info that says you may experience duplicate icons in this scenario and that some folks solve it by blocking the .lnk extension from getting synced.

Always exclude .lnk from OneDrive sync, even for physical PCs

was hoping someone wouldn't say that. .lnk files are pretty popular, network shortcuts, app shortcuts, etc... Thx for the tip.

The your other path is to remove duplicates https://github.com/aaronparker/remediations/tree/main/Shortcuts-Duplicate

i dont suppose there are any articles that 'officially' say you should block .lnk files? Or is that more just expereience with it over the years?

There's nothing official, but if you don't you run the serious possibility of getting duplicate icons, as you've seen. Worst culprit was Edge.
