IBM Notes, (formerly IBM Lotus Notes) is how a modern business connects using enterprise email.
The IBM Notes enterprise email client integrates messaging, business applications, and social collaboration into one easier-to-use workspace. IBM Notes goes wherever you go, helping you work smarter and faster to provide better business results.
With the IBM Notes Email Connector, users have the ability to search Notes emails directly from within SharePoint or another portal. Security defined within IBM Notes is automatically reflected in the search experience, so users will see search results from their own mailbox, public mailboxes, and other mailboxes for which they have been granted access.
