Outlook allows you to export your calendars and events to the default calendar app(s) on Android. This allows you to easily view and edit them via the default calendar app.
Navigate to your account within Settings. Then, tap Sync Calendars.
Two-way calendar export is supported for Microsoft 365, Outlook.com, and hybrid modern authentication for on-premises mailboxes. Two-way support ensures that any new events you add or existing events you edit will be synced between your device and your Outlook accounts.
If you'd like to remove the synced calendar and events, you can toggle the Sync Calendars switch at any time and they will be removed from the default calendar app(s).
