Backing up IMAP Emails using MS Outlook Has Become Simpler

An Outlook account which is configured with an IMAP mailing server keeps a copy of mailbox data of the server on the local device. This replica of data is stored in an OST file (Offline storage table) which makes recovering data easier in case of connection loss or other disturbances. But it is always advisable to keep a backup of data and update it on regular intervals.

Backing up Outlook data is free of hassle till the Outlook version 2010 because data was used to store into two different files, one for emails and another for Contacts. To keep the data secure users could maintain each file separately and nullify the security threats. Also, backing up the folders individually was much easier than restoring the whole data in one place.

But after the introduction of Outlook 2013, restoring data has become quite complicated as the IMAP accounts of later versions are quite difficult to handle. In this version, appointments, tasks, contacts, calendar, and notes are stored in a single OST file which means one file store a lot of stuff, backing up which seems a hassle, especially to the novices. The place where data is stored separately is the “user’s view”. On the Outlook’s interface, the data other than emails are stored on a file named “This computer only”.

With this storage mechanism, it is only possible to recover all mailbox data except Calendars, and contacts. This data is saved on the local machine only. So situations like accidental deletion, virus infection, hard drive crashes and sudden format can cause the data loss from Contacts, and calendars. So, it is advisable to manually restore the data from the OST file. There are possible ways to manually recover the data from Outlook folders.
