Last week, Microsoft released a security update for the Skype for Business 2015 client.
MS15-097: Description of the security update for Microsoft Lync 2013 (Skype for Business): September 8, 2015 – Microsoft Support

Make sure you have all prior security updates installed before installing this one! They are linked on the same page, under “More Information.”

I saw a mention of this on Twitter, right after a ZDNet announcement about troubleshooting Windows 10 problems.

Which led me to talking with co-workers. After hearing some of their newer stories, it was time to blog.

I currently run Skype for Business on Windows 8.1. Haven’t switched to Windows 10 yet, but I’m sure it’s coming soon. Many of our customers are in the process of switching to Windows 10 now. We anticipate about half of them will move within the next 6 months.

Like ZDNet, we’re starting to see issues.

The Skype4B Issues Appearing on Windows 10

Not all our customers use Skype for Business. Of those that do, most users report no problems. Only a handful have called to report some issue, like:

  • Skype for Business hangs on the load screen
  • Skype for Business client loads, but immediately crashes
  • Random “Microsoft Lync has stopped working” error messages

What we’re finding is that, for a very few users running Skype for Business on Windows 10, the OS was actually the culprit!

In one case, Cortana prevented Skype for Business from receiving calls. The user didn’t need Cortana, so we disabled it (her?). Skype for Business commenced proper operation after a reboot.

Now, these are both Microsoft software applications. They should get along, right?

It appears not. (To some degree at least.) So, with this in mind, let’s do something a little different this week.

Having Skype for Business Issues on Windows 10? Please Vote in Our Survey

I’d like to request all of our readers respond to this survey:
[yop_poll id=”6″]

Just a few questions. If you’re experiencing something different, please use the “Other” field.

Our reasoning for the survey is twofold. One, if we can identify bugs in communications between Skype for Business and Windows 10, we’ll submit the data (anonymized of course) to Microsoft Support.

Two, the more we know about real-world Windows 10 issues currently popping up, the more we can study them. Try to replicate them in our datacenter. Figure out solutions.

The survey will run until September 30th. After that, I’ll compile the results and bring them to the rest of our Lync/Skype team. Any & all observations reached will go up on this blog.

I’d also appreciate if you share this post on social media. The more respondents we have, the more real-world data we can compare. I’ve added simple sharing buttons to the bottom of this post.

Thank you for participating! If you have questions, please feel free to comment or email me.
