Introduction
Whenever you create an Exchange, IMAP, or Outlook.com account in Microsoft Outlook for Windows, an Offline Outlook data file (.OST) is created at a default location. This Offline Outlook data file (OST) contains a local copy of the server’s mailbox items. As a result, even when the system is offline or not connected to the internet, you can access emails and perform pending tasks.
However, when a user mailbox is deleted from the server or an account is deactivated, the OST file becomes orphaned and unreachable. You cannot import or open an OST file in another Outlook account, unlike a PST file, because it is encrypted with the MAPI EntryID GUID.
Furthermore, synchronization issues between the Exchange server and the OST file can cause an OST file to become inaccessible. When the Exchange server or database that holds your mailbox crashes or dismounts, this can happen. Unexpected power outages, system or Outlook crashes, virus or malware infestation are some of the other factors that might also harm the Outlook OST file.
You can use an OST to PST converter software, such as EdbMails, to extract your mail items from an inaccessible or orphaned OST file and save them to an Outlook PST file in all of these scenarios. Emails, attachments, contacts, notes, tasks, journals, and other mailbox objects can be immediately exported from inaccessible, damaged, or orphaned OST files to PST, Office 365, or a live Exchange server using the software.

Verdict
Even though the Offline Outlook OST file is reliable and resilient, it can be damaged by a sudden system shutdown, Outlook crash, or other factors. Furthermore, if the mailbox is deleted from Exchange or the mail server, the OST file may become orphaned and disconnected. OST files cannot be read or imported into any Outlook profile because they are encrypted and require authentication from the connected MAPI profile.

The software is highly recommended since it converts OST to PST faster and extracts all data with 100 percent accuracy.
