Add/Edit Exchange Online (Personal) Source - Panel

Your email messages are received in and sent from a mailbox hosted on Microsoft Exchange Online server. When you have the required privileges, you can thus add an Exchange Online source to make the content of your Exchange Online mailbox searchable (messages, conversations, contacts, attachments, archives). Only the creator of the Exchange online source can see and search its content. The source starts a refresh every 15 minutes to index content file changes (additions, modifications, or deletions) so that they become searchable shortly after. When you have more than one Exchange Online mailbox, simply create one Exchange Online source per mailbox.

Administrators could edit and rebuild your source, or set your source permission type to Shared to see your mailbox content in the Content Browser (see Source Permission Types). Also, setting your source permission type to Shared allows any user (authenticated or not) that can access your search interface to see the source content. It is thus recommended to only create Exchange Online sources for mailboxes that contain no sensitive data.
