In Microsoft Outlook, both OST and PST files are necessary. On the system set with Outlook, OST files are used to save the offline copy of the data from the Exchange Server.

Let us know everything:

OST to PST Conversion has many benefits for Outlook users. For example:

• After converting an OST file to a PST file, you can save the PST file in a secure place.

• For this reason, offline OST files must be converted to PST file types.

Difficulties In Convert OST File to PST Mannually:

It is not difficult for users to recreate OST data files when Outlook is linked to Exchange. However, it is not feasible to recreate OST files if your Exchange Server is unavailable, either indefinitely or momentarily. In this case, an OST to PST Converter tool is required for your offline Outlook data file. When attempting to convert OST files to PST manually, customers encounter a few difficulties.

• Users cannot access an OST file using a different account or a different Exchange account. The same Exchange user account is required. The Exchange account that was used to build it is the sole way to access it.

Then, you are unable to generate your OST file to replace a corrupted one while your Exchange Server is down. That's the point at which OST file conversion by hand is not feasible.
• Exchange mailboxes containing orphaned Outlook OST files are unrecoverable: Orphaned OST files are OST files that are not associated with your Exchange server. An orphaned OST file is the only place where a user's mailbox data is kept safe when Exchange crashes. Surprisingly, orphaned OST data files cannot be converted manually. The only way to convert OST to PST file that are linked to your Exchange Server is by hand.
