When the profile or mailboxes on the Exchange or IMAP server are deleted, the OST file becomes inaccessible.

Taking into account all of these factors, we examine the features of EdbMails that we believe are the most user-friendly.

Features that makes EdbMails the best OST to PST converter

OST recovery features

Recovery of inaccessible OST files

EdbMails outperforms other tools in terms of speed since it quickly recovers inaccessible OST files and converts them to Outlook PST from what we tested. When compared to other tools, the user interface is simple and clear. It also allows you to save the recovered OST file in EML, MHT, and HTML formats. Another intriguing feature of EdbMails is its granular recovery, which recovers all items such as emails, contacts, calendars, and tasks without missing anything.

Recovery of corrupt and damaged OST files

We wanted to put EdbMails’ recovery feature to the test again, so for testing purposes we used an OST file (1GB file size) which was corrupted due to problems with Microsoft Outlook. We were unable to open or access this OST file and used EdbMails to test its functionality. We must say that this tool performs excellently and recovered this OST file without any hitches. We even double-checked some of the mail items and can say with confidence that it is full-fledged software on steroids, that maintains complete consistency and even allows you to read the mail from its interface.

Keeps track of metadata in PST

Following that, we tested the meta-data properties such as Received Date, Sent Date, Time, To, and Cc, as these are important for legal and other backup purposes, as well as verification. We tried converting an entire mailbox, and EdbMails was able to output all of the contents while retaining all of the properties.

Maintains the structure of folders

The ability to keep the exact folder structure is also an important feature of any file converter tool. We don’t want to open a file and find that the content has changed and that we have to rearrange everything again, do we? Surprisingly, EdbMails retains a mirror of the source’s folder structure on the target with no loss or changes and preserves the internal organization and hierarchy.

Direct migration of OST to Office 365 or live Exchange

Another remarkable feature we discovered is the ability to directly import mailboxes from an OST file to Microsoft Office 365 or live Exchange. This is especially useful for users who want to move directly to the Office 365 cloud without any intermediate hops or conversions. We tested the EdbMails import feature with a trial Office 365 account, and it supports incremental migration, which prevents duplicates by migrating the contents from the same PC to the same target.
