Chosen solution
I have all desktop alerts turned off I prefer it this way I don't need all of that. I just want to be able to look and see new message. Even if I have an account with zero message I need to click to see the new ones there are no numbers appear. I am also running QuickFolders and its the same nothing shows up on those tabs until i physically click on them. Ok so my mistake the Properties option is there when right clicking folder - I was only focused on right clicking on the email address to take me to server setting I was not clicking on the actual folder. I right click a folder and Properties and it take me to attached windows.

I did see a response from a MS person that said it was working as intended, that it wouldn’t refresh the folder until it was selected. Although that seems like a load of BS, but could just be a con to try to migrate people to exchange at a higher cost. I know that sometimes when doing it, it can take a moment for the rest of the folders to kick back in.
