Hi all,
Got a rather strange one. We have an new install of Skype for Business Server 2015 Enterprise edition (with May 2021 patches) running on windows 2019 server, with clients using Skype for business 2019 (16.0.10374.20040).
Chat, persistent chat, screen sharing etc are all working just fine.
WhiteBoard, Poll and Q&A, do work, but ONLY on the 2nd try. First try always fails, with the following message shown in the Skype Client
"Whiteboard [1] can't be uploaded to the meeting." in a pop-up and "An Error occurred while sharing" in the Client.
Anyone got any clues?
Thanks in advance
