How Microsoft Purview DLP currently can help you protect confidential data in Copilot.

on
Organizations today face a difficult balancing act. Business leaders are eager to adopt tools like Microsoft Copilot to unlock productivity and innovation. Meanwhile, IT and security teams are concerned about safeguarding sensitive information, especially as AI-driven features process vast amounts of organizational data. This tension is real: enabling advanced capabilities without compromising compliance or data protection is a challenge every modern enterprise must solve. Microsoft Purview Data Loss Prevention (DLP) is a key solution to this problem. It provides mechanisms to prevent confidential data from being exposed or misused, even in scenarios involving AI. I want to highlight two features designed to help organizations in controlling what is being processed by Copilot. Blocking Documents Based on Sensitivity Labels One of the foundational features of Purview DLP is its ability to enforce policies based on Microsoft Information Protection sensitivity labels.

Installation error when upgrading Exchange 2010 to SP1

on
I encountered a strange issue when I upgraded an Exchange 2010 installation just the other day. I could not find any technet articles or other blog posts with anything similar to my error. So I thought I'd share my error and solution.

The installation is a rather small one, so I have all the roles co-located on one server.

First of all, I was not able to upgrade using GUI at all. It told me I had to select components, even though all the components were already selected. It just gave me a nonsense error message. It was only after disabling the UMserver (as suggested by this document: http://technet.microsoft.com/en-us/library/ff630921.aspx) I was able to run the wizard.

Unfortunately I was still not able to install the service pack from the GUI. I then tried to run the setup.com /m:upgrade /installwindowsfeature from command prompt. The setup still feiled. When studying the error setup logs (great logging of the setup by the way) I noticed it was complaining about not being able to read the language-packages. And this is where I was puzzeled: The setup was looking for the languagepack on the desktop of my administrator account, not in the setupdirectory I was running setup from.

My simple solution to the problem was this: Copy all the language folders to the desktop. I rebooted the Exchange server (A failed install will need to be rebooted before running setup again) and ran setup.com again. And this time it worked just fine.

Anyone with a good explanation on the placements of the language files? Please drop me a note in the comments section ;)
