Hi Everyone, We have just rolled out Skype for Business (O365) and have discovered that when logging in, SfB puts a client authentication certificate in the Users Personal Certificate Store. This is troublesome for us because we use client authentication certificate to secure things like Remote Access.

If you are a Skype for Business Online user, use username@domain.com. Otherwise, use domain username. If you have questions about your sign-in address, contact your workplace technical support team. So I have a Skype for Business deployment and I am having an issue at the edge with external users and guest users not being able to join audio or share their screen.

Users are now being prompted with a certificate prompt identical to this blog post: I've tried the steps described in the blog post which looks super promising but alas, the certificates are still generated in the Personal Store instead of the intended LyncCertStore. Has anyone else worked with Lync or Skype for Business and managed to get around this issue or have any insights for us? For-mar nature.

Thanks in advance, Adam. Forgot to mention: HKLM SOFTWARE Policies Mic rosoft Off ice key did not exist for me initially.

I have tried to create the path (15.0 and 16.0 just in case) and the DWORD as described, no go. See attached screenshot (1.JPG). The LyncCertStore itself has been created and is visible in certmgr.msc. Each time I 'delete my sign-in info' I confirm the certificate has been removed (2.JPG).

Each time I sign in again the certificate comes back in the Personal Store (3.JPG). I hope I'm not missing something idiotic or just misreading something. Vasil, would you mind including a screenshot of your registry and your certmgr.msc LyncCertStore please just so I can do a sanity check? Thanks for taking the time to test and comment. Until I hear back I'll reinstall SfB and see if that changes anything for me. Thanks again, Adam.
