Missing messages in new OS X client
Hi Clare. Are you using SFB Mac with O365, Skype for Business 2015 or Lync Server? I think you are running into a known issue where Server Side Conversation History may have not enabled. SFB Mac depends on Server Side Conversation History to correctly handle missed message.
Server Side History requires Exchange 2013 and newer. I am running Exchange 2010 SP3 so I cannot enable Server Side History. This makes the Mac client useless as every message I send to a Mac user returns a "We couldn't send the message" warning, even though the message is in fact received.

Hi Gordon. Does the person who send you the message see this error for the first message of the conversation? Or does the sender see this error even you are already in the conversation wtih them?
