Four Microsoft 365 Copilot Features That Will Make Your Workflow Easier

on
Microsoft has announced four Copilot updates, some already live or in preview, others rolling out soon, that are designed to simplify tasks, improve control, and boost productivity. These enhancements include smarter content referencing, flexible reasoning modes, customizable response scoping, and integrated meeting scheduling. Timelines may change, so keep an eye on official updates.  Copilot Chat Enhancements: Reference Files and Emails Easily Copilot Chat for users with a Microsoft 365 Copilot license is being enhanced by introducing quick access to emails directly in prompts. By typing “/” in the prompt box, users can search and reference relevant content without manual uploads, improving prompt quality and Copilot responses. Suggested prompts beneath the input box will also include relevant files or emails for faster starts.

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.
