Hello,
To narrow down your issue, I want to confirm:
1. Would you please post the whole message or error?
2. When does this issue occur? Which function do you mean? Does it occur on all Skype for Business client?
Normally, to troubleshoot Skype for Business client issue, we can try:
1. Install Skype for Business update, and
update to date.
2. To prevent add-in affect, run it
safe mode (lync.exe /safe).
3. Clear the Skype for Business
cache:
a. Navigate to the
%localappdata%\Microsoft\Office\16.0\Lync folder.
b. Delete your
sip profile folder.
c. Go into the
Tracing folder, delete the all files, but not the folders).
4. To prevent application affect, try Windows
clean boot, and test the results.
Best Regards,
Allen Wang
