Microsoft Copilot is all around...

  As the debut of Microsoft 365 Copilot approaches, there are a lot of Copilot features set to be introduced across the Microsoft 365 ecosystem. Here are a few noteworthy additions: Microsoft has unveiled a series of innovative features in the upcoming releases of Windows 11, some of them are already released, and some are currently available in preview builds. The Windows 11 Copilot, conveniently located in the taskbar, eliminates the need to open your Edge browser. It is seamlessly integrated with Bing Enterprise Chat (BEC) and ChatGPT, making it really easy to get started on your creative journey. Included in Windows 11 is the new co-creator feature in Paint. This feature, also in preview, is integrated with DALL-E and provides a swift and straightforward method for creating illustrations and images. If you possess a knack for crafting descriptions, you can generate quite impressive imagery. Another AI-powered feature is image creation directly from BEC. This feature, also integrate

Lync client may connect to a non federated partner, even if you though it should not.

Here is an "interesting" observation I did a couple of days ago. The customer has chosen not to allow DNS discovery of federated partners, but will allow federation with selected partners on the allow list. After a while with this configuration, the customer called me and told me they had mixed experiences with the solution. There were times when meetings with a partner (NOT on the allow list) actually would work, even if they expected the meeting to fail.

They asked me to verify the settings, and to investigate why some users reported they could connect to a meeting others couldn't.

This is what I saw on a client who failed to connect:

5 messages. And the interesting one would be the 504 message: "Can not route".

And then the client stops trying, as I would expect it to.

But here is an interesting twist. Log on with the same client from a remote connection (through edge), and then let's see what happens.

The client does not honor the 504 message "Can not route". It continues and connects to the meeting, unexpectedly. How can that be?

The interesting part is what happens after the 504 message. First the client acknowledges the rejection, but then it does something it didn't do on the inside. There is a new invite, trying to connect anonymously:

And this connection is allowed. Quite confusing for the end user, actually. But now they know.

It is important to note the user was allowed for federation in this scenario, but the domain in question was not in the allow list and DNS discovery was not allowed. Also, the organizer on the other side was allowing anonymous invites.
