SharePoint Calendar: Enterprise Management Guide

SharePoint Calendar Enterprise Management Guide (2026)

SharePoint calendars in 2026 span modern Microsoft 365 SharePoint Online calendar lists, Microsoft Lists calendar views, Microsoft Teams channel calendars, Microsoft Exchange shared calendars, and Microsoft Power Automate-powered calendar automation — all governed by Microsoft Purview sensitivity labels and integrated with Microsoft 365 Copilot for scheduling intelligence.
