Safeguarding Sensitive Data in Microsoft 365 Copilot with Purview DLP (GA Release)

on
The challenge with sensitive data and access to Copilot Microsoft 365 Copilot empowers users with AI-driven assistance across Microsoft 365 apps, but it also raises concerns about accidental oversharing of sensitive information. In response, Microsoft has extended its Purview Data Loss Prevention (DLP) capabilities to Microsoft 365 Copilot, allowing organizations to enforce information protection policies within AI workflows. The DLP for Microsoft 365 Copilot has been in preview for some time, but Microsoft has now announced it is released for GA (General Availability). Among some of the interesting features are new features like alerting and policy simulation. Key details:  Rollout Timeline: As of June 2025, the rollout has begun. It should be completed worldwide by late July 2025. Scope: Initially, DLP for Copilot was available for Copilot Chat scenarios. By the time of GA this is expanding to Copilot in core Office apps (Word, Excel, PowerPoint) as well. Ensuring that DLP prote...

More additions to the Backup-SfB script

on
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.
