How the maximal number of contacts in outlook.com can be increased from 6500?

Hi,

I'm testing the outlook.com as a gmail alternative,

But I see that I have an issue to import my contacts as I have 7500 contacts, and it limits me to 6500.

It says: "your address book cannot contain more than 6500 contacts"

In addition there are several additional limitations as company name length no longer than 40 letters and no more than 1024 letters in the note area.

Can I increase this limit?, it was understandable from the publications that it's limitless.

Thanks,
