New Year, New Momentum: Here are three Copilot updates to get you started into 2026

It's a new year, so I thought I'd start the year by mentioning three features already released, or soon going to be released. One of the features improves the workflow of sharing files with comments, the other improves the application specific Copilot, and the last feature makes it easer to find the nest available timeslot for a 1:1 meeting. As with all of my other posts, timelines can shift, and the timelines in this post is as written in the Message Center at the time of posting. AI-Summary experience when sharing files.

Guest Access will be default "on" for Teams

Here is a heads up for all Teams admins:
- ".. to bring Teams Guest capability into alignment with the rest of the suite, where the setting is already on by default." Microsoft is changing this policy (Allow Guest Access) to on.

But if some reason you need to turn this off for the entire organization, you will need to do so manually once this setting has been deployed.

According to "Message ID: MC228482" in the admin message center, this should start rolling out on February 8th.
