Thank you for your reply. You are right, but my new contacts, which i created on the phone, appeared in "Suggested contacts" in my Outlook.(active Sync, corporate e-mail). I just moved them from "Suggested contacts" to "Contacts" in my Outlook, and they synced back to my Phone. I am not sure that this is a Google problem, because several of my colleagues who also are on Lollipop(Xperia Z3, Galaxy S5, Note 4, all stock Lollipop without any modifications), never have mentioned any thing. I will discuss this issue with them.
