Microsoft excel stock data not updating today, May 16th, is this a know issue?

I agree totally Michael. I would have thought a lot more people and businesses would complain. I also dont have updated asx stock data on Bing. I did my cumulative update late on 14 May just before turning my computer off for the day, then no share data from either the 15th or 16th - so i think you are correct that something in that update is related to the issue. We just have to hope that more people contact microsoft to complain. The spreadsheet im working on doesnt function correctly without the latest data. :(

Again, it's the same thing when you look up Australian stock prices on Microsoft's search engine www.bing.com. It also uses the same datasource. Of course they haven't updated since the 15th of May either.

It is very odd that more people aren't' complaining. I'm reasonably sure that the problem coincided with the 2025-05 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems last week.

Confirms MS need to sort this
