Skype for Business messaging skype user

Yeah I did not seem to have any issues when I logged into skype from my outlook account. But when I create a summy account or have a user create and log in with a abstergoex4.com or starlabs.fr they have a difficult time messaging me and even adding me. I began testing this on a wednesday and sent myself a request and it arrived yesterday to my Skype for Business acount. The worst part besides the 5 day wait is even after I accepted the request it still showed afterwards the presence was unknown. This is a huge problem becuase the majority of the people I communicate with skype have non-business accounts and I dont want to have to set up tons of accounts to deply to users. I wish they would make some improvements on this problem.
