AC Question

Hi,
I have a Samsung S5 and recently having some strange activity please bare with me on the length of the story.

My Outlook.com email account keeps getting 'unusual sign in activity' emails and lists the IP as 195.124.9.141, which is a German IP, when I check MX toolbox it comes up as ns0.fra.samsungsocialhub.com and is registered to a company called Samsung SDS. I have removed all accounts from my S5 (facebook, whatsapp etc) and the emails still come into my inbox, once a day at different times. I have enabled 2 step verification on my account and still the emails arrive. I haven't even opened Samsung Social Hub on my S5 so unsure what is going on.

Has anyone heard of this issue and can help me out, thank you.
