Best OST to PST converter: EdbMails software Review


Anyone who has used Microsoft Outlook knows how difficult it is to convert an OST file to a PST file. If Outlook is unable to sync an .ost file with the Exchange or IMAP mail account server, the file becomes inaccessible. When Outlook is syncing with online accounts, there is also the possibility of faulty updates or an improper system shutdown that might orphan the OST. Another issue is the portability of OST files. Because an OST file is usually associated with an account, copying it to another PC is not possible.

Everyone desires a quick and simple method for completing a task which is quite the same case  when converting OST to PST. Despite the fact that Outlook includes tools for converting OST files to PST files, the process is time-consuming and labor-intensive. Furthermore, using Outlook to convert an unavailable or orphaned OST file is pointless if you can’t access it in the first place. This is where an OST to PST converter, such as EdbMails can quickly and easily convert inaccessible or orphaned OST files into Outlook PST formats. Continue reading for a comprehensive review of the software.

EdbMails OST to PST software – An Overview

This OST to PST converter program can easily convert large OST files to PST files (without size limitations). The software granularly extracts all offline Outlook data file files such as attachments, emails, notes, tasks, calendars, contacts and so on preserving their uniqueness and consistency. This is also retained when converting from OST to PST, with no data loss or changes occurring during the process.

EdbMails works with all Exchange and Outlook versions, from 2003 to the most recent 2016 and 2019. Furthermore, the software is compatible with all Windows Operating System and Server versions, ranging from Windows 7 to the most recent 10 and 11.

This software allows you to save OST files in EML, MHT, and HTML formats. This is useful if you want to open and check your mail from multiple apps, such as a web browser or notepad.

EdbMails OST converter includes a free demo version that allows you to convert an OST file to a PST file (with 30 items from each folder restriction). There are three distinct pricing plan flavors designed to meet the needs of different users and requirements: Personal, Corporate Premium, and Technical, each with their own set of functionalities.

EdbMails OST Corporate Premium Edition, for example, allows you to directly import the contents of an OST file into an online Office 365 or live Exchange account, in addition to supporting OST to PST conversions. This makes things a lot easier when a company switches from one email domain to another and needs to transfer mailboxes directly in less time without any intermediate steps or other complications. The Technical Edition is similar to the Corporate Edition in that it can be installed on multiple PCs and in multiple locations. It is appropriate for data recovery companies and maintenance companies that want to use the license to provide data recovery to their customers.
