The error log sfbmac.log shows that there is some server timeout but really I don't know how to read it. Well, I contacted my support team and was told 'Buy a PC, We don't support Mac.' So much for the Workplace support team. Before that, Skype for Business Mac worked for a couple months error free. These messages after a Skype update about a month or so ago but I don't recall the build when the problem started. Other days I get the message every 19 minutes or so for hours on end. If this continues, contact your support team.' Somedays I do not get the message. I'm getting a Skype error message 'We're having trouble connecting to the server.
