Bookings made in Nexudus appear in the resource's calendar, and events added in Outlook become bookings in Nexudus, usually within a few minutes. The integration is free. It's for your team; customers can connect their own Outlook calendar from the members portal (see [Integrations on the members portal](/member-portal/profile/integrations)). ## Before you start * **An Office 365 account** you own, with access to its calendars. If you use a Microsoft organisation, the account needs **Mailbox** and **Calendar** permissions. * **Matching time zones** — make sure Outlook and your Nexudus location use the same time zone, or booking times will be out. * **A calendar for each resource** — in Outlook, use **Add calendar → Create blank calendar** for each resource you want to sync, named after the resource. ## Connecting Office 365 1. Go to **Settings → Integrations → Office365 calendar** and select **Connect**. 2. Sign in to your Microsoft account and select **Yes** to allow access. 3. Back in Nexudus, choose the **Office365 calendar** for each **Resource**, or leave it on **Not controlled by Nexudus**. 4. Save. Office 365 settings ## Booking from Outlook Add an event to the resource's calendar at a quarter-hour start and end time — bookings at other times are saved in Outlook but not synced. If your Outlook email matches a customer, the booking is theirs. To book for someone else, add their email as the first **Attendee**; if it doesn't match a customer, assign the customer to the booking in Nexudus. ## Related * [Scheduling and calendars](/integrations/scheduling) — all scheduling integrations * [Microsoft Teams](/integrations/scheduling/microsoft-teams) — booking from inside Teams This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
