Sharing your Copilot notebooks - Is being rolled out

on
Microsoft is rolling a new update to Copilot Notebooks that make collaboration even easier: the ability to share Copilot Notebooks with your colleagues.  Personally, I like Notebooks because they feel almost like small, personal agents I don’t have to configure. They give me a safe space to collect notes and documents and then work on them over time. With this update, that personal space can become a shared space for a selected group of  colleagues, without compromising security or permissions. I think it is also important to note that your chat and chat history within the Notebook stays private. The web rollout began in late October and will finish by December, while mobile access starts in early November and are related to the Microsoft 365 Roadmap ( ID 506851 )  You can also read more about the Copilot Notebooks experience on the Microsoft website here . If you like this update and want to stay informed about similar improvements, feel free to follow me on LinkedIn!

502_3 bad gateway IIS AAR RP for Lync

on
I encountered a "new" error message this week, as I was finalizing a Lync 2013 deployment for a customer. When I say new, it was new to me, as I had not seen this before. Everything was set up for remote access and federations, but certain features, such as mobility did not work right away. I decided to test the URL's from the outside, and was surprised to find the following error message:


This deployment was set up with a IIS ARR for reverse proxy. I searched for the 502 (502.3 to be exact) on forums and internet in general, but could not find any answer to my exact issue.

I verified firewall ports and connectivity was ok. I also checked the web sites on port 4443 and 8080 from a client inside, and saw no apparent errors.

I went through the deployment guide one more time (step by step), and discovered I had forgotten to import the internal CA ROOT to the Reverse Proxy machine. Once this was installed, it all worked just fine.

The reason I decided to write this post, is because the root cause was not very obvious to me (only after reading tracing logs and checking the step by step guide again, was I able to figure out the problem). And I wanted to write a reminder to myself, and maybe help somebody else if they happened to forget to import the ROOT CA.

The 502 "invalid response" can be a lot of things. Certificate error being one of them. Now I know.

For those looking for a guide to set this up, I have two links for you:
This is the one I used: http://uclobby.wordpress.com/2013/08/02/configuring-arr-for-lync-server/

And here is one from nexthop: http://blogs.technet.com/b/nexthop/archive/2013/02/19/using-iis-arr-as-a-reverse-proxy-for-lync-server-2013.aspx

I preferred the first one, as it was a more "general" rule to catch all. But it might not suit all scenarios. The one from nexthop is much more detailed, and will have you set up a rule for each URL.
