Outlook OST file?

OST or offline storage table (.ost) file is an offline Outlook data file stored on local user. It is created in collaboration with Microsoft Exchange Server that enables users to work with their messages and mail data even when accessing mail server isn't possible. In offline mode, when you try to send or receive email through your MS Outlook then it asks you to create OST file because MS Outlook cannot send/receive your message as Exchange server is not connected. In this mode, your all worked data gets stored in OST file at specific location. Next time, when Exchange server connection with MS Outlook get established properly, your offline or OST file data get synchronized with Exchange server database. In fact, OST file is just a replica of Exchange server user mailbox.
