Backup Exchange mailbox using OST file

How to Backup OST File of Outlook 2019, 2016, 2013, 2010 using EdbMails

Exchange Online does not allow you to perform a traditional mailbox backup. That is, it is not possible to restore a mailbox to the state it was in when the backup was taken. If you require a backup of the mailbox, you can import it from the user's Outlook if it is configured with an Outlook profile as an OST file.

Offline Outlook Data or OST files are stored by email servers in Microsoft Outlook. They contain a copy of the cloud mailbox data for instance from Office 365, Exchange server and IMAP accounts. OST files are created by enabling the Cached Exchange Mode option in MS Outlook . These files can work offline and the mailbox data in the cloud is kept synchronized with the local OST files when an internet connection is available.

Reasons for backup and conversion of OST file to PST

• Local OST files are prone to corruption, virus infection, unexpected system shut-downs, hardware failure events, ransomware threats etc.
• OST files are orphaned due to Exchange server failures.
• Difficult to completely recover corrupted OST files manually A cached OST file does not reflect the current mailbox contents on the server making it difficult to retrieve important data that has been lost recently.
• Syncing issues of overgrown OST files with MS Outlook.
• Accidental deletion of folders and files in Exchange server.
