Good Morning SharePoint Community,
I am doing my homework to try to find the real impact of the User Profile Service Application, but I thought I should ask more seasoned SP Admins, thus I'm coming to you all. A little background on the questions I'm about to ask is that I have 6 SharePoint Farms. In about half of them the User Profile Synchronization Service refused to start after we switched them to TLS 1.1/1.2, then I was able to fix it by making sure all settings were correct and we installed an update for the SLQ Native Client which was the reason why UPSS wasn't starting. I have spent countless hours debugging my UPSS. I was able to fix it in most my farms but after installing the November 2018 patch my user profile synchronization service will not start in at least two of my farms. I have basically rebuild the user profile service application a couple of times in my environments and it is now broken again. I'm about to take the mediocre route of not caring about starting my User Profile Synchronization Service anymore...
My question is:
What happens if I don't start the user profile synchronization service in my farms anymore? Will it have a very negative impact on my environment?
I don't mean to have you do my "homework", I just want to know your opinion based on your professional experience.
Much Obliged!
