Typical use cases
How the Outlook Add-In works
The add-in is provided as a Microsoft 365 app via the M365 Admin Center. After installation, it appears automatically in Outlook and activates when an appointment is sent (OnAppointmentSend event). Communication runs through the anny API. Users authenticate with their Microsoft account. The add-in requires read access to calendar entries and basic profile information.Connecting the Outlook Add-In

Setting up visitor registration
To register visitors directly from the Outlook Add-In, you need at least one resource in the visitor registration category with at least one booking option. As soon as such a resource exists in your account, the Register as visitor icon appears next to participants in the add-in. A room booking is not required for that. Set the resource up so it matches your reception:Create the resource and booking option
Prepare check-in and the host
Time forms and signatures

Limitations
- The add-in only works with Outlook version 2206 (build 15330.20196) or newer
- On-premise installations may require a manual adjustment of the mailbox version in the manifest
- Visitor registration only appears if at least one resource in the visitor registration category has a booking option
- You can only register participants set to On site. With Remote, the icon is disabled. An existing registration is removed
- The organizer (host) has no registration icon
- If you change the appointment time, visitor registrations that have not been sent yet are cleared and must be applied again
- Rescheduling by an appointment owner other than the original booker can lead to new bookings instead of changes
