Configure Appspace Space Reservations Add-In for Outlook 365

Appspace has developed a new plugin, or add-in that integrates the Appspace Space Reservations system with Microsoft Outlook, allowing users to directly book resources and workspaces configured in the Appspace reservations system, from a Microsoft Outlook desktop or web client. For organizations using Microsoft 365 (previously Office 365), the solution offers integration with Exchange resources.

This feature integrates and synchronizes the Appspace Space Reservations capabilities with Microsoft Outlook appointment forms to provide the following capabilities:

  • Installable as an add-in to the Microsoft Outlook desktop client and web client. Supports Office 2016 or greater.
  • Displays an Appspace Places button in the Microsoft Outlook Meeting ribbon in the Appointment tab.
  • When the Appspace Places button is clicked, a Appspace Places pane is displayed on the side panel in the appointment/meeting request form.
  • The Appspace Places pane can be toggled On or Off.
  • Users can search for a meeting space if one hasn’t been selected in the location field of the meeting request form.
    • Once the user selects a meeting space, the location field is updated with the appropriate Microsoft Exchange resource.
    • If the date and time has been selected in the Outlook form, apply filtering to the Appspace add-in.
  • The Appspace Places panel allows users to filter/search for the following:
    • Building
    • Floor
    • Zone (if a floor has zones)
    • Workplace type (Room or Space)
    • Workspace (Subtype)
    • Status (Available & Unavailable)
    • Room capacity
    • Facilities
  • Users can Apply/Cancel/Update/Delete the meetings.
  • Users may also create, edit, or delete the meetings on behalf of another employee, if their O365 account has been delegated by the booking account used to authenticate the O365 plugin.

Configure the Appspace Places for Outlook 365 Plugin on MS Outlook

Space Reservations Administrator

The Appspace Space Reservations administrator is required to select the default calendar authentication passport that will be used in order to integrate the Outlook 365 plugin with the calendar provider that is used for Reservations. This passport will be used by default to search any resources/rooms by email once the plugin is installed.

Follow the instructions below to select an O365 passport to integrate with the Appspace Places Outlook 365 add-in:

  1. Log in to the Appspace console.
  2. Click the ☰ Appspace menu, and click Integrations.
  3. Click the Passports tab, and click the +ADD button.
  4. Select Office 365, and click Next.
  5. Select the preferred permissions as described below:

      • Application Permissions – Application permissions are the recommended approach to connecting Appspace to Microsoft Office 365 as this will natively allow you to sync any meeting room calendar resource to Appspace. You will also have the ability to use the Outlook Add-in and book on behalf of features within the Appspace platform without having a complicated O365 configuration.
        You will still have full control over the resources you would like to sync when setting up the provider. You can also use Microsoft Application Access policies configured in O365 to restrict the scope that the Appspace application has access to.
        Application permissions enable apps to run without a signed-in user present, allowing it to run in the background. An administrator account however is needed to just authenticate this passport and the permissions.
      • Delegated Permissions – Delegated permission gives Appspace access to Microsoft Office Calendar Resources based on the permissions of the service account you use to authorize the passport. This will require the service account to be added as a full delegate to each calendar resource needed to sync the information from and to Appspace and Office 365. This can include Meeting Room Calendars as well as possibly users’ calendars if utilizing the Outlook Add-in and book-on-behalf feature.
      • User Permissions Only (Does not sync resources ) – User permissions uses the delegated permission model and is very similar to the Delegated Permission option. But this option only includes access to users’ calendars based on delegated access to each user’s calendar. Use this option if you want a dedicated passport for the Outlook Add-in and book-on-behalf.
        For more information on the passport permission types, between Delegated (Admin and Basic user) and Application permission, please visit the Permissions and consent in the Microsoft identity platform here: 
  6. Click CONNECT.
  7. Proceed to authenticate the passport, and grant permissions to access the calendar provider account. You may be required to sign in with your calendar provider credentials if you are currently signed out.
  8. Follow the on-screen instructions to continue to configure the calendar provider passport.
  9. Once authenticated, in the Account Settings tab, you may perform the following actions:

    • View and refresh the Status of the passport.
    • Remove the passport, by clicking the Remove Account button.
  10. In the Permissions tab, you may grant the following users or user groups permissions to view or edit this passport configuration at any time:
      • Enter and select the user(s) or user group(s) from the drop-down list, or click the Find users or user groups link, and select the desired user(s) or user group(s). Proceed to grant either Can Manage or Can View permissions by clicking the Select permissions drop-down menu.
