Mattermost caps Professional plan at 250 users
What happened
Between the May 4, 2026 and May 11, 2026 captures of Mattermost's pricing page, Pulse recorded one change: Professional plan now explicitly states a 'Maximum 250 Users' limit, introducing a user cap where no cap was previously documented. Pulse files it as a packaging change (limit decrease) with a downward direction.
It lands 36 days after Mattermost's previous change, "Mattermost narrows InTune MAM mobile support to iOS only" (Apr 6, 2026). Before that Pulse recorded "Mattermost Adds Burn-on-Read Messages and InTune MAM Support" (Apr 4, 2026). Mattermost has been tracked since 2023-11-15.
In the same window Microsoft and Slack also changed their Collaboration & Productivity pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
