Microsoft 365 updates on new Copilot capabilities

Microsoft has announced a set of upcoming enhancements that continue to expand the value of Copilot across Microsoft 365. These updates introduce new ways for users to manage collaboration and meeting experiences with less context switching and more control. As always, timelines may shift as development progresses. I have provided the official reference IDs and documentation links for your convenience. Schedule meetings directly from Copilot Chat The first update introduces a new capability that allows users to schedule meetings directly from Copilot chat. This feature reached general availability worldwide with rollout completed by late January 2026. It enables users to find available times, book rooms, draft agendas, and send invitations entirely within the chat experience, reducing the need to move between applications and helping streamline everyday workflow.

Batteling the Mediation server (or; this time we blame Cisco)

I'm sorry I haven't posted in a wile. But I have been busy doing other implementations. The two last days however, have been more quiet (Easter is almost upon us in Norway). I have now tried to install a mediation server, and connect the OCS world to the rest of the world through a SIP trunk to CUCM (v7).

Installing the mediation server, adding a certificate, and configuring dialing rules and routes was pretty easy. I've made one simple rule for internal dialing with 4 extensions, and one for the rest of the world (for testing purposes limited to dialing the Norwegian dial plan).

Setting up the trunk on CUCM seemed fairly easy to, but I do however have on problem with the configuration I set up. And if any of you out there have a solution to it, please let me know :)

Dialing from a Cisco phone to a pure MOCS extension is working with RTP in both directions. But when dialing from MOCS and out, all calls are blocked with a 503 (Service unavailable) message from the CUCM. I can see the call in CUCM's traces), and I see the same when tracing on the Mediation server.

I've searched around, and tried to figure out what is wrong. The only thing I think might be it is a problem related to how the OCS uses + in front of numbers when calling. There is a fix for this in OCS 2007, but it is not released for R2 (at least yet).

I have verified translation patterns, css and partitons on CUCM. And the digit analyzer is giving me an OK.

Does anyone out there know the reason for the 503 error code? (The SIP trunk is unsecured and is set to use MTP)
