Just got confirmation back that the IP has been de-listed.

Still not sure why it was listed in the first place.

Checked the IP and can't find it in any other blacklists, I wasn't using it at all until yesterday so I doubt it's anything i've done, seems Microsoft have decided to blacklist a load of OVH Ip's for some reason.

Have requested De-listing so we will see if microsoft get around to it or not.
