Sending email invites from the Mac client
We ran into a similar issue - but found that the users' sign-in address for Skype for Business for Mac didn't match the authentication information for Outlook 2016.
We had to change the Skype login to match the authentication user@domain.com so both matched and were able to get it to work. There are a lot of other posts indicating that the credentials MUST match between the two.
They do match. Further, it works on every platform besides Mac with the same credentials.

Same issue here. Double checked that signed in to SkypeFB with same email as Outlook, but getting this error (after first sending - I get a beep and it doesn't send, then try again and spinning for 5+min):
You must be signed into Skype for Business (Lync) before working with online meetings in Outlook. Sign into Skype for Business (Lync) and try again.
Confirms this functionality WORKS when sending internally to the company, but not externally to other o365 users on another domain. Any suggestions? Is there a hidden Skype id somewhere that I should be using instead?
