European Collaboration Summit, 5 - 7 May 2026, Cologne/Germany
No, you can't.
The European Collaboration Summit has earned its reputation as the Microsoft 365 conference that actually delivers. No fluff, no empty promises — just product roadmaps and visions delivered by Microsoft people building them, and practical insights from people doing the work.
Here's what makes it worth your time and travel budget (and why the smart money books early).
Microsoft engineers don't just deliver keynotes and disappear. They attend sessions, eat lunch in the main hall, and genuinely engage with attendees. Product managers take actual notes during feedback sessions. When else can you explain directly to a Teams developer why that latest update is causing chaos? This level of access is rare and remarkably productive.
Forget theoretical frameworks and 'digital transformation journeys.' CollabSummit speakers share the actual solutions - scripts, workarounds, and configurations - that solve real problems. When someone presents on SharePoint migration, they include the PowerShell scripts. GitHub repos are shared. This is knowledge you can use immediately.
Beyond the usual promotional giveaways, the expo showcases ISVs and partners solving specific Microsoft 365 gaps. Need a governance tool that actually works? A backup solution that covers what Microsoft doesn't? It's here. Better yet, the booth staff are often the actual developers who built these solutions. They understand edge cases and can discuss technical details, not just pricing tiers.

"Every organization struggles with Microsoft 365 quirks. SharePoint permissions that make no sense. Overshared Teams. Copilot suggestions that miss the mark entirely. At CollabSummit, these challenges are discussed openly. The value comes from hearing how peer organizations navigate these same issues — and which solutions actually work."
Teams that learn together win together. CollabSummit is the perfect environment to align, explore, and grow as a unit. You'll build shared understanding and come home energized with a common vision — and likely, a few exciting new ideas to try out right away.
Sending multiple team members amplifies the benefits exponentially. While one person covers governance sessions, another explores Copilot workshops. Teams leave with shared understanding and aligned priorities — something no amount of internal meetings can replicate.
With 3,000 attendees, CollabSummit hits the sweet spot — large enough for diverse perspectives, small enough for meaningful connections. The same faces appear throughout the event. Conversations that start in session queues continue over coffee. The run.events and WhatsApp groups formed during the conference remain active year-round, becoming valuable professional networks.

Speaker, Microsoft
"It has been an epic week at the European Collaboration Summit. As always the organisation was impeccable with everything running smoothly! The benefits of these conferences are huge - I used some learnings yesterday when I returned to work, I have a head full of ideas about how I can demo some really cool features, and I have ideas about how I can tell stories better."
Attendee
"I attended the European Collaboration Summit and was able to gather many ideas and learn about new developments that we can immediately integrate into our collaboration and M365 projects."
Attendee
"The European Collaboration Summit (ECS) 2025 in Düsseldorf was a real highlight for me – not just because of the inspiring sessions. I was able to take something valuable from every session and went home with a head full of ideas – now it's time to put them into practice and dive deeper."
With over 3,000 attendees from across Europe and beyond, CollabSummit is the largest Microsoft 365-focused conference in the world. But what makes it special is the atmosphere: warm, welcoming, and driven by community spirit.
Whether it's your first conference or your tenth, you'll feel right at home. The conversations don't end when the sessions do — they continue over coffee, lunch, and shared ideas. By joining, you become part of something bigger.
While other conferences leave attendees inspired but directionless, CollabSummit sessions end with clear next steps. Speakers share specific resources, answer follow-up questions in community channels months later, and provide the actual tools needed for implementation. Attendees leave with concrete plans, not just abstract ideas.
With Copilot deployments accelerating, SharePoint becoming a backbone of the whole Microsoft 365 platform, and Teams evolving constantly, staying current isn't optional. CollabSummit sessions offer the full picture — successes, failures, crucial lessons learned, and the immportant next steps.

Every month you wait to get this knowledge is another month your organization falls behind.
The companies sending teams to CollabSummit in May will be implementing solutions while others are still reading documentation.
"Here's the thing about CollabSummit: it consistently sells out. Not because of marketing hype, but because people who went last year immediately book for next year. The tutorials cap at 50 people and fill within weeks. Cologne hotel rates triple closer to the event."
If you're thinking about it, you're probably going. The question is whether you'll pay early-bird rates or scramble for last-minute tickets.
