ExtendSync Outlook | Learn why add-in are grayed out or missing on certain mail items

Updated over 3 months ago

Outlook add-ins are available on messages or appointments while composing or reading, but not other item types. Outlook does not activate add-ins (they are grayed out in ribbon bar) if the current message item, in a compose or read form, is one of the following:

  • The reading pane is hidden (View > Reading Pane > Hidden)

  • Protected by Information Rights Management (IRM) or encrypted in other ways for protection. A digitally signed message is an example since digital signing relies on one of these mechanisms.

  • A delivery report or notification that has the message class IPM.Report.*, including delivery and Non-Delivery Report (NDR) reports, and read, non-read, and delay notifications.

  • A draft (does not have a sender assigned to it), or in the Outlook Drafts folder.

  • A .msg or .eml file is an attachment to another message.

  • A .msg or .eml file is opened from the file system.

  • In a shared mailbox, in another user's mailbox, in an archive mailbox, or in a public folder.

  • 👉 Update, see this article to check if your Outlook supports add-ins for shared mailboxes

  • Using a Custom Form.
