It's these "private" email providers. They have their access from third party clients usually barred. I didn't really care since I was using web client for my personal email anyways. Also I only switched because my old provider went tits up and I had to either switch or start paying for the same service for more money for the one who acquired them. Only thing I miss is having all my email accounts in one place. Not really for the shared contacts or calendar, but for the convenience.
