EdbMails OST to PST converter: Handy tool for OST conversion


An OST to PST Converter’s goal is to convert your Outlook OST file into an Outlook PST file. Offline Storage Table (OST) refers to the offline Outlook data file created by Microsoft Office Outlook when used in combination with Microsoft Exchange Server. In other words, when you configure an Exchange account in Outlook on a Windows computer, the contents of your mailbox are saved in an OST file (i.e. Outlook.Ost file). As long as you have Internet access, the OST file synchronizes with your mailbox on the Exchange Server. When you lose internet connection, all the changes are saved in this locally stored .ost file. Before we discuss and review an OST converter tool, we’ll go over some of the fundamentals and requirements for file conversion to gain a better understanding..

OST to PST conversion requirements

You can access your mailbox even if you are not connected to the internet because the OST file is saved locally on your laptop or desktop computer. You can use your mailbox’s contents in the same way that you do when you’re online. Every single change made in your mailbox (i.e. in the OST file saved on your PC) when you were offline is synchronized with the mailbox contents at the server as soon as the Internet connection is restored. Because Outlook can now synchronize your local mailbox with the one on the server, you’ll have instant access to all of your recently received emails.

When you work with an IMAP or a POP3-based email account, such as Gmail, Yahoo! Mail, HotMail or others, Microsoft Outlook creates a portable PST file to save your mailbox contents. You can save it as a backup copy of your mailbox on your hard-disk or another location and then import it into Outlook as needed. To take advantage of features such as mailbox backup and portability, it is necessary to convert the OST file to Outlook PST file format. It is also possible in some cases that the Exchange server will fail, leaving you with an orphan or inaccessible file and no choice but to convert the OST file. In such cases, it is strongly advised to use a professional recovery tool, such as EdbMails, which is discussed in detail in the following sections..
