Read add-ins activate in the Reading Pane or read inspector of Outlook. Unlike compose add-ins (Outlook add-ins that are activated when a user creates a message or appointment), read add-ins are available when users:
-
View an email message, meeting request, meeting response, or meeting cancellation.
[!NOTE] Outlook doesn't activate add-ins in read form for certain types of messages, including items that are attachments to another message, items in the Outlook Drafts folder, or items that are encrypted or protected in other ways.
-
View a meeting item in which the user is an attendee.
The location of an add-in in the Message Read surface depends on your Outlook client.
-
Windows (classic), Mac: Select the add-in from the ribbon of the Reading Pane or read inspector.
