Recovering ost file in Exchange 2003

Someone restored backup to Exchange 2003 Datastore. The mailbox once logged in merges all the changes from restored data into the local .ost file with no emails missing.

Later users complained that there mails missing in the shared mailbox accessed through Outlook.

This seems like .ost file doesn’t merge the data not belonging to its own mailbox/ of another mailbox. Could be let me know resolution as how to merge the shared mailbox data into user’s mailboxes.



For OST file recovery in disaster scenario is to login to the user mailbox in offline mode and extract ost file into pst file and then copy that data again from PST file to recovered mailbox after logging as online mode.

For reference
