This error frequently occurs in Outlook OST files, and it happens when Outlook does not synchronize with Exchange Server. Every email client uses a contact list in Outlook, and this contact list refers to the Offline address book (OAB). OAB looks like a GAL (global address list) that is there in the Exchange Server mailbox. The exchange server is containing the user detail contents like names and email addresses used by Outlook. Due to OAB’s presence, Outlook doesn’t have to connect to Exchange Server every time the user sends the mail.
