Hi all,
when trying to sign in to Skype for Business, I am told that signing in is not possible because of
problems with the DNS-configuration (error code KB2566790). The DNS entries have been changed according to this article:

Unfortunately, signing in still doesn't work. My company hasn't purchased Office 365 so I was wondering if that might be the reason for my problem.
So please tell me if purchasing Office 365 will allow me to sign in, or if that's not the problem, tell me about possible solutions that you know.
