Stop adding unwanted names to my phone contacts
I use my phone contacts for phone calls, not for emails. I don't appreciate having unwanted names from my Outlook e-mail automatically added to my phone contacts without my permission, especially when duplicated multiple times. It takes me too long to scroll through my phone contacts now, and I don't have time to go through all of them to delete the ones I did not add in the first place.
And stop picking up contacts in folders which have been marked as "not to be used as an address book", many people have hundreds or even thousands of archived contacts we want to keep without being forced to wade through them on our devices, you know, like it works in Outlook, only use contact folders marked to be used as an address book. The flag has been there for years, why stop using it now that it's more useful than ever!
