2/20/2025: Please note that thottling/blocking has now been enabled for all versions of Exchange Server...
Thanks for your reply to my previous post KevinShaughnessy , it was a few days later that the report finally updated to showing the Green and Red statuses, so it does look like they have made progress. However, I have a new question that is similar to others, but I think attaching these screen shots would help with what we see in our tenant.
So as before, I am on 2016 with 4 active and 2 passive servers, and got it all the way up to 15.1.2507.39 as recommended. The report online does show them in Green and powershell output shows the matched versions. However, this is where I see an issue, is that there are 2 versions of the same server listed, with 1 being out of date and the other compliant. The only difference is that one has the name of the server and the other has the FQDN, which is the one that is Green. (Names have been hidden)
When you look at powershell, it lists the same server 3 times.
What I am afraid of, is that it will block the one that just has the name and not the FQDN, causing a throttle issue. I enabled my pause for 30 days, so I have until 6/22 to find out if throttling will occur, since there is no way to turn the pause off once enabled. Do we know if that will matter? I don't think it will, as a few of them should have started seeing throttling/blocking in the last 2 days and the report doesn't show it, but I think this might be a representation of what some are saying about the report showing servers out of date, even though they are actually compliant.
