8x8 Work for Office 365: Meetings Add-In Installation Instructions for Users and Administrators


The 8x8 Work for Office 365 meetings add-in gives users the ability to create and share meetings directly in Microsoft Outlook 365 (online).

This guide will show:


Note to end users: This guide is specifically intended for users of Microsoft 365 accounts which are centrally managed by a Microsoft 365 service administrator. In this case, a Microsoft 365 administrator must deploy the 8x8 Work for Office 365 meetings add-in for their end users to see or install it.

If your Microsoft Office applications are not centrally managed by your IT service or other administrator, please see the following article, instead:


Applies To

  • 8x8 Work for Office 365
  • Microsoft 365
  • Microsoft Outlook 365 (Online version)
  • Microsoft accounts that are centrally managed by a Microsoft 365 administrator


For Users:

If the add-in was automatically deployed to users by a Microsoft 365 administrator, the 8x8 Work icon clipboard_e8962792a8bb007579f2b6b4091b87075.png will already appear in the top ribbon of a New event in the Outlook Calendar.

If the 8x8 Work icon does not appear in the calendar New event ribbon, click on the More actions ellipsis clipboard_ea16c5c6d6fa33258aeefa3f0ccdfa94c.png in the ribbon to see if the add-in is displayed there. If you don't see it, then the add-in will need to be installed.

Important-Icon.png If you don't see the 8x8 Work icon clipboard_e8962792a8bb007579f2b6b4091b87075.png in the Calendar > New event action ribbon or in the More actions menu (clipboard_ea16c5c6d6fa33258aeefa3f0ccdfa94c.png), and it cannot be installed from the Add-Ins for Outlook marketplace, please contact your IT department or Microsoft 365 administrator to have the add-in deployed.

  7. Click on the 8x8 Work icon clipboard_e8962792a8bb007579f2b6b4091b87075.png to display the 8x8 login prompt.
