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

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. That’s better than users copy‑pasting sensit...

More additions to the Backup-SfB script

The Backup-SfB script was just released, and keen eyes might have noticed the version 4.00 has been updated to 4.00 C by the time of the release.
I had several beta testers run the 4.00 release, and most of them ran it without too many comments. But I received two important requests:

  1. Please try to minimize error output from the script
  2. I don't know how to capture certain devices.
So here are the three minor, yet important changes to the script

Backup Common Area and Analog Devices
This request was simple enough: Neither the user nor the db backups hold any information on Common area phones or Analog devices. That's why the "backup-basics" function now will run get-cscommonarephone and get-csanalogphones and pipe it to a couple of csv files in the bakcup directory. 
From these files, it should be easy enough to import the information required back into SfB upon restore through a script.

CS Announcements
Although this information is present in the CMS configuration, I was asked if not this could be added as a standalone extra in the same way as the polices and voice settings are.
As it only took two lines of code, I decided it was a good idea to do so.
Included in the bakup are now two new files. A list of unassigned number ranges, and a list of cs announcements (The voice prompts should already be a part of the file backup)

Error handling
Error handling isn't my strongest powershell skill. After all, I'm only a UC techie trying to learn this stuff. But I have been requested on several occasions to quiet down the blood red text in the output of the script. In order to do so, I have now set the default error and warning handling to -silentlycontinue, unless you use the -DebugSQL switch.

I have tried to capture any missing backup files we would expect, so please read the transcript for errors. And then run the script again, with the -debugsql switch to capture the real error.
