iPhone contacts and Exchange server aren't syncing
My contacts on my iPhone and my Exchange account used to sync seamlessly until about a year ago. Now when I go into my Contacts and look in Lists, I see that there are more contacts listed under All Contacts than either my "All Exchange" or "All iPhone." How do I set this up to ensure that when I add a contact on my phone, it gets synced to Exchange? Is there a way to ensure that they're forced to sync now so that I don't have to figure out what ended up saved in the wrong spots?
iPhone 13, iOS 16
