“Bring your AI to work” is here: Microsoft edition - What Multiple Account Access to Copilot means

on
Multiple Account Access to Copilot On October 1. 2025 Microsoft released a blog post explaining how employees now can use Copilot from their personal 365 plans to work on organizational data. This is of course, an extension of the already existing "Multi account" feature that was released for corporate accounts a "couple of months" ago. In other words, “bring your own Copilot” is now a real thing in Word, Excel, PowerPoint, Outlook, and OneNote on desktop and mobile, with enterprise protections intact. “Bring your AI to work” is an important topic, and banning AI altogether might not be the answer. Whether sanctioned or shadow, AI has already entered everyday knowledge work. Microsoft’s new multi‑account access offers a safer path where employees can use Copilot from their personal Microsoft 365 subscriptions on work files, while the file’s access, auditing, and compliance still flow through the work identity and tenant.

A couple of favorite news from the world of Teams last week.

Another week has gone by, and it has not been a week without announcements or releases around Teams or Skype for Business. Here is a little recap of what I consider the highlights of last week.

On Teams

If you are into development, Microsoft launched a new site/collection called "What's new for developers in Teams".  And is a great collection and a starting point for developers. https://docs.microsoft.com/en-us/microsoftteams/platform/whats-new

Auto-favorite a channel was released as a feature, allowing admins of Teams to help users mark important channels as favorite. Users may still un-favorite these channels, but this can be a useful feature for new users to different teams.
Other features this week is:
  • Send a message from the command box
  • Send a chat from the contact card
  • Preview and edit Visio files
  • Get a reminder that your team is expiring
Techsummit in Sweden is over, and one of many great sessions was the one on security and compliance by Anne Michels. here deck is available at the Techcommunity.

On Skype for Business

Cu7 was released recently, and with that a capability to turn of support for TLS1.0 and TLS1.1. Now, a word of caution, because doing so in the wrong way could lead to some issues, and I really recommend reading through the guide at NextHop in advance. Losing federation is one of the possible issues. Please read these posts carefully:

On OneNote

The team behind OneNote announced the future of OneNote (as part of Office) and OneNote for Windows 10. https://techcommunity.microsoft.com/t5/Office-365-Blog/The-best-version-of-OneNote-on-Windows/ba-p/183974 
In short terms: If you want all the best and new features, you need to use the "app store" version of OneNote. It is basically replacing the Office version from now on.
