Microsoft is adding offline calendar support to the new Outlook app

Microsoft has been bringing a number of new features to the Outlook email app lately. Just the other day, the tech giant announced that you’ll soon be able to switch freely between the new and classic Outlook apps, and now they’ve announced that soon you won’t need to be connected to the internet to manage your Outlook calendar.

In the roadmap of upcoming Microsoft 365 features, there’s an entry for “Outlook: Offline Support for Calendar” that mentions “you’ll be able to create, edit, and delete events in your calendar when not connected to the internet.” The rollout is expected to start in June 2025 and will be for all users with general availability.

However, this offline calendar support only seems to apply to the new Outlook app. If you want to keep using classic Outlook, note that you’ll still have to be always online to manage your calendar.
