🌃🎶 Cool night air, a hot sauna and some retro jazz. Having a week between two international adventures sure is good for some much-needed downtime 🙏

Grabbed a Too Good To Go surprise bag in Oslo from BIT Union. Just over 4€. Got this massive cornucopia of good stuff. 😛 Who says Norway is always expensive??

Sunday cooking time again.. pan-seared chicken hearts, spicy ajvar, garlic, eggplant and herbs. So good! 🔥

It's somehow been a full year - but I'm back in Bremen again for CollabDays, preparing tomorrow's demos and listening to jazz from the tinny phone speakers in my hotel room. The döner & dürüm kebabs are still exquisite & are the first item on my to-do list whenever I get to Germany. A tradition.

Just watched the movie 'A Complete Unknown' covering the early days of Bob Dylan's career. Brilliant stuff, I highly recommend it!

Been thinking about why insider risk is so widely misunderstood (thought to narrowly only mean malicious active employees) or outright neglected compared to attacker focused cybersec. Probably because technical signals aren't enough. You need business context, human knowledge & more to succeed.

New work earbuds arrived! 👍 It was time for an upgrade after my old Mpow X5s finally gave up after 5 years of loyal and meritorous service. 🎧 The WH-1000XM5s have been my daily driver headphones all year so going for the buds as well was an easy call, especially after some recommendations.

A pause in the rain coincided with a few of the short hours of daylight we get now so it was time for a Sunday trip to explore the icy forests ❄️🌲 The slippery icy paths glazed with meltwater made for a different kind of adventure.. but equipped with a thermos of hot tea, I had a good time 🍵

Maybe it's a cultural thing and probably I'm just super cynical - but many (not all!) posts in which people say they are "deeply humbled", "super excited", "truly inspired" etc. about mundane professional stuff seem.. not genuine? It feels like performative emotional hyperbole.

Reading some Roman history 📖 Some of the stuff in the Twelve Tables - an early code of laws from around 450BCE - is still surprisingly relatable. "Should a tree on a neighbour's farm be bent crooked by the wind and lean over your farm, you may take legal action for the removal of that tree." 🌲

A thing I've come to value in people is the ability to say "I don't know" - and more importantly, "I don't know, but let's find out" Building our identities around being people who know stuff isn't sustainable. A more healthy dynamic is to focus on curiosity, learning and gradual evolution.

Earlier this month, I delivered my last session of the calendar year at the #ESPC24 conference in Stockholm on building custom Microsoft 365 Copilot usage analytics. It seems like people enjoyed the talk - the session received a solid score of 9.38/10. A nice way to wrap up the year! 🙏 Onwards.. ➡️

Microsoft Authenticator passkey auth has really grown on me lately 🌱 Easier and faster to use than app-based notifications, with MitM&Replay resistance to boot? Yes please. Even the initial registration feels pretty simple now. ✅ #EntraID #Passwordless

Did you know you can configure separate #Purview retention policies for #Microsoft365 #Copilot & Enterprise app Interactions? When configuring via PowerShell, remember to use Set-AppRetentionCompliance and not Set-RetentionCompliancePolicy. #Microsoft has not updated its documentation yet.

Oof, configured a #microsoftpurview on-prem MIP scanner discovery + auto-labeling deployment this week that uses nearly every single non-baseline / edge case configuration option simultaneously, some of which weren't even documented. Upgrading from v2.X to v3 was well-doc'd though, kudos for that. 🙏

Another day, another undocumented #MicrosoftPurview limitation. 🥱 Turns out you can only add <=1000 exceptions to an All Users scoped sensitivity label publishing policy with the "Set-LabelPolicy -AddExchangeLocationException" PowerShell cmdlet. Why isn't this stuff in Learn? 🤷‍♂️

Ok, so.. *all* M365 Copilot licensed organizations will get the SharePoint Advanced Management addon bundled in early next year. That's actually solid. I'm positively surprised. Source: www.microsoft.com/en-us/micros... #SharePoint #DataSecurity #Governance #M365Copilot

(1/N) More #MSIgnite highlights for #MicrosoftPurview: 🆕 Extend protection to docs dl'd/copied from SharePoint by syncing doc permissions to SPO site permissions. Requires SharePoint Advanced Mgmt addon. Only works with unencrypted docs. Essentially applies UDP encryption at time of download. Cool!
