We've recently rolled out Skype for Business (Microsoft Lync 2013 10.0.4745.1000) MSO 32 bit, onto our Windows 7 64 bit, office 2010 32 bit systems nationally.  We rolled it out using SCCM 2012 R2.

Prior to the rollout, we were on Lync 2010 32 bit, and the use of group blast chats were used for announcements always successfully.  After upgrading to Skype for Business, this is no longer consistent.  Many clients, receive texts for the group chats but the content is blank.  They do not have this issue with one to one chats.

We have gone so far as to have the senders delete all old contacts in outlook 2010 and remove and re-add the contacts in Skype for Business.  On the receiving end, we had the clients search for any old contacts for the senders but deletion and re-add didn't resolve this.

At this point I'm putting the question out to the forum as there hasn't been much by way of input on the web that I've seen.

If anyone has any ideas, please advise, thank you.
