Microsoft's Jeff Teper - SharePoint at 25, Past, Present, and AI Future

Who should listen: Microsoft 365 service owners, SharePoint and intranet administrators, and information governance leads planning Copilot readiness, oversharing remediation, or the move to the new SharePoint navigation and design language.

Guest: Jeff Teper — President, Microsoft 365 Collaborative Apps and Platforms, Microsoft

Jeff Teper, President of Microsoft 365 Collaborative Apps and Platforms, marks SharePoint's 25th anniversary with a look back at its origins in Site Server and the FrontPage server extensions, the painful multi-tenant cloud transition, and the MySite feature that IT switched off and which later became OneDrive. He also sets out the refreshed SharePoint design language and five-pillar information architecture, and explains why reasoning models finally make zero-shot content tagging and AI-assisted site building viable.

Key insights

SharePoint came from two separate Microsoft efforts merging — Teper's Site Server / Tahoe PKM publishing and knowledge management work, and the Office team's FrontPage server extensions — deliberately shipped as one customisable family rather than separate document management, intranet and collaboration servers. ▶ 3:08
A new workflow customisation experience built on Power Platform but surfaced with a simple UI inside SharePoint and Teams has just entered preview — the modern answer to the list-based workflows that built the original community. ▶ 6:10
Bill Gates announced multi-tenant SharePoint Online at the 2008 SharePoint Conference, but neither customers nor Microsoft's own multi-tenancy tech were ready; even by the 2014 conference many customers still said management would never allow a cloud move. Teper's view: the cloud shift went 99% of the way, with edge cases such as Navy submarines. ▶ 7:42
Current platform scale: over a billion users, 5–10 million requests per second depending on time zone overlap, and many exabytes of data — from a server that ran under Teper's desk in 2001. Roughly 2 million new SharePoint sites are created every day. ▶ 9:14
MySite was rejected by IT — the first time Teper saw customers buy a product then deliberately disable a feature — and only came back as OneDrive under competitive pressure from Dropbox; migrating over a billion OneDrive accounts onto the SharePoint platform took a herculean engineering effort to make SharePoint cheaper and more elastic to run. ▶ 10:14
Auto-categorisation was tried in 2001 using Support Vector Machines with Microsoft Research (Susan Dumais, Eric Horvitz) and needed around 50 training documents per category, so nobody used it. Reasoning models now do the same tagging zero-shot, populating product and customer columns across a library without training data. ▶ 13:51
SharePoint Advanced Management — permissions reporting and oversharing analysis — was the biggest seller in SharePoint Premium, and Microsoft then bundled it free with a couple of hundred Copilot licences; usage is now growing rapidly because it addresses the oversharing fear blocking Copilot rollouts. Where IT does not trust the ACLs, sensitivity labels can exclude whole sites from Copilot. ▶ 25:11
On shipping cadence and defaults: Teams ships every two weeks and Microsoft has stopped agreeing to six- or twelve-month deployment trains, but big UX changes get staged — threads in channels ran three months in preview after three months' notice, and the new SharePoint navigation is opt-in during public preview before any decision on on-by-default at GA. ▶ 30:17
The new SharePoint information architecture is five items in the left nav: your branded intranet home (absorbing Viva Connections), Build, Publish (absorbing Viva Amplify), Discover (the Delve idea reborn) and OneDrive as the modern file explorer across all SharePoint and Teams libraries, plus a new design language with flexible, column-free layouts. ▶ 33:53
