presence unknown when I try to phone or message contacts

Copper Contributor

Hi, I recently moved to a different office for my company. My old colleagues still show on my contact list. Some of them still show as busy or available, some of them show as presence unknown. However when I try to phone, message them etc, they all show as presence unknown. When I left the office on Friday, they were having problems with Skype then, If we phoned each other it was showing as presence unknown, because they were changing our e-mail address's on outlook. However for reasons we won't go into I'm a little worried that they have blocked me. Any help would be gratefully received, as I am climbing the walls.
