@GossiTheDog yeah a "BUG"
@lexinova a bug. As in a digital "listening" device planted by Microslop for (at least the) US police/authorities to hoover up all that juicy confidential data somewhere else.

For some reason it hasn’t put out a security advisory - but instead buried it in a service alert which isn’t publicly visible.
So the AI assistant designed to help you write documents is now deleting your documents
At some point we need to ask: are we adding AI because it solves a problem, or because someone in a boardroom decided every product needs an AI checkbox for the next earnings call
This is what happens when you ship features to impress investors instead of users

@GossiTheDog while generating summaries might be a benefit. Why delete the original mail? How can one implement such a feature so lousy? (rhetorical question)
[Edit] that mail gets deleted was an assumption on my part based on "data loss prevention" in the text. It might not be the case. And the issue is only that E-Mails are summarized while flagged to not get summarized in one view of the app.

@GossiTheDog more about problem and fix here with Tony Redmond @TonyRedmond (Office365ITPros): https://office365itpros.com/2026/02/13/dlp-policy-for-copilot-bug/
"Bug", "Code error", exposing sensitive data. Yeah, nah. I'm sure that's it. Who got the data? Microslop? Gargle? Whose hands did it end up in? Hmmm.

@GossiTheDog I literally had a supervisor excitedly sharing news on Friday that we would be rolling out ChatGPT for organizational use and how it was approved for editing confidential documents. I sent back a private reply that yeah, you better not believe that for an instant.
I just forwarded this link, can't wait to see the reply.

@GossiTheDog The bug is "The warnings come at the end of the email", presumably.
