Outlook May update adds shared calendars and Copilot
Microsoft rolled out May 2026 updates to Outlook that bring automatic visibility for shared calendars in the new client. Teammate calendars now appear in the navigation pane without manual setup. Users can also select text in classic Outlook and pull Copilot insights directly from it. Multi-select controls got richer and web users gained .ics export. The changes address long-standing gaps between the two Outlook versions during the ongoing migration.
Before this update, anyone switching between classic and new Outlook faced inconsistent calendar views and had to manually add shared mailboxes each time they moved devices or accounts. Coordination across teams stayed fragmented because calendar data lived in different places depending on which client someone opened. Now the gap narrows, but the underlying problem remains. More calendars surfacing automatically increases the volume of events people must scan without reducing the actual coordination work required to decide what matters.
Analysis
Skip the feature tour and instead open new Outlook this week, locate every shared mailbox your role actually touches, and decide which calendars belong in your main view versus hidden. Do it before the rollout makes the choice for you.
