"I've just got a new phone and want to synchronize all my phone numbers between Live Mail and HTC 10. What do I do? Here's what happened. I searched the solutions on the internet, and one of them says that if I create my Windows contacts as vcf files and transfer them to my phone, I'll be able to have them in the People app. But, when I've done this, they are nowhere to be found. I don't get it. Can anyone help me?"
When finishing reading the following parts, you will find no difficulties in this. And the method is not just suitable for HTC 10. You can actually sync contacts between Windows Live Mail and HTC 10/One A9/M9.
For the problem above, my answer is that there is no need to do this because you can have it done on your computer directly. Sometimes, phone users may be confused by how to transfer data between different systems. Why bother if you have tools to do all the work? Use Android Manager, then. It is aimed to offer a package of solutions for people to deal with Android files. What's more, you can even edit the contacts on it.
Now, please download this program and follow the steps.
