I keep reading in the forums that there is a known bug in Skype for Business 2019 on-premise.
We are unable to send messages to public Skype users by using their registered email address. For example, we are attempting to send an IM to a public Skype user with the email address of (a*****@gmail.com) and are receiving a message "The action couldn't be completed. Please try again later".
I have followed all of the directions listed on https://docs.microsoft.com/en-us/skypeforbusiness/deploy/deploy-skype-connectivity?toc=/SkypeForBusi...
Yet we still can not use this feature. Is this error part of the known bug that is expected to be addressed in the Skype for Business 2019 CU?
