Frequently asked questions
How to convert OST to PST from Outlook 2021, 2019, 2016 and 2013?
Here are the steps to export OST to PST file with EdbMails
What is the difference between OST and PST?
An OST (Offline Storage Table) file is a local copy of your mailbox that is stored on your device. It enables you to access the email data when you are not connected to the Exchange server. An OST file is synchronized with the Exchange server when a connection is established, ensuring that all changes made to the OST file are reflected in the Exchange mailbox.
On the other hand, a PST (Personal Storage Table) file is a separate file that is used to store and backup email data, contacts, calendar items, and other Outlook data. PST files are stored on your local device and can be easily backed up, transferred, or imported to another device.
See OST vs PSTHow to resolve the error Outlook OST cannot be opened?
EdbMails can resolve the errors ‘Outlook OST cannot be accessed’, ‘Outlook profile.ost is in use’ and 'Errors have been detected in the file outlook.ost' by converting the inaccessible OST file to PST or migrating it to Microsoft 365 and Live Exchange thereby restoring all of the mail data.
Can I open an OST file in EdbMails without using Outlook?
Yes. EdbMails can open an OST file without Outlook dependency. However, if you would like to convert your mailbox and folders to PST, then you need to have Outlook installed on your system. You also do not require Outlook if you are migrating the OST to Microsoft 365 or Exchange server.
Why convert OST files to PST files?
Corruption of OST file: If an OST file becomes corrupted due to Outlook crash, hardware failure, or other issues, converting it to PST can enable you to access the email data again.

Upgrading to a New Version of Outlook: When you upgrade to a newer version of Microsoft Outlook, the OST file from the older version may not be compatible with the new version. In such cases, converting the OST file to PST format can help you to synchronize your emails with the newer Outlook.
Backup and archiving: By converting OST to PST, you can create a separate backup file making it easier to protect your email data in case of a disaster or other issue.
How to recover deleted mail items and folders from an OST file?
