On a mac running latest OS sierra with all updates I have installed Skype for business for mac - and already have office 2016 for Mac (office 365). When I try to sign in to the skype, just as on other mac, a new popup appear from office 365 that 'this doesn´t look like a valid user ID'. There is a username and password line - where on the username it is only standing my initials. If I add my email adress, it start to load, but then just jumps back to the main login page of skype for business. I tried to create new keychain and also log in as other user on the computer, but the problem is the same. I don´t know if it is something with the office 365 activation that is wrong, even the office package works fine.

Hi Rossoneris, Since you've got an error message saying that this doesn't look like a valid user ID, I'd like to introduce an article to you for your reference: If the problems persists after referring to the article above, I'd like to collect some more information to troubleshoot the issue: 1. Please give me a screenshot of the error message for analysis. Regarding 'I tried to create new keychain and also log in as other user on the computer, but the problem is the same', do you mean that this issue happened to multiple users inside your organization? Have you deployed a special environment for your Office 365 organization such as ADFS, Hybrid, on-premise Skype for Business server, etc.?
Is the Skype for Business for Mac the latest one? Did this issue happen only when you signed into Skype for Business for Mac with a specific Mac machine? If you sign into Skype for Business for Mac with your Office 365 account on another Mac machine, does the same issue happen? Regards, Mouran. Hi Rossoneris, Thank you for the updates. 
Yes, I agree with you.

Since the user has no problem signing to Skype for Business for Mac on other Macs running same version, it means this is a specific Mac problem. Here I’d like to offer you some more suggestions: 1. Upgrade the Skype for Business for Mac to the latest version. Trying deleting the sign-in info by clicking the “Delete sign-in info” button. Collect the logs by clicking Skype for Business > Preference > General > Collect Logs and send me the log via the private message for further analysis. Some Lync profiles might be different from Skype for Business on Mac profiles and can cause a discrepancy. You can and reinstall it to see if there is any improvement.
