SFB client Instant Messaging will initiate a Skype call instead of sending the message RRS feed

  • Question

  • Not sure if anyone of you have encountered this weird behaviour with Skype for Business client. A few of our users reported that when they are about to answer/respond to an Instant Message in Skype for Business, the SFB places/initiated a call to the other party automatically. Previously, I advised them to reboot the computer and it did helped but recently some of them said that even after rebooting the problem persist. For those who have experienced this same problem, please share with us your solution. Thank you.

  • Hi EVM06,

    For this issue, I suggest you could try to check the following:
    1. Check the SFB version in those users’ PC, if possible, please try to update the SFB client to the latest version.
    2. Try to perform a clean boot in Windows to check if it works. This will helps eliminate whether the issue is caused by software conflicts.
    3. Try to clear SFB cache files as below:
    SFB client cache file: %Userprofile%\AppData\Local\Microsoft\Office\16.0\Lync\sip_XXXXX
    SFB Registry: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync\sip_XXXXX

    Best Regards,
