Outlook is one of the most prevalent platforms for conducting daily email interactions. Over the years, Microsoft Outlook has launched different versions, such as 2021, 2019, 2016, 2013, & 2007, to become more user-specific with their advanced algorithms and robust features.

Configuring your account to be associated with IMAP, Exchange, or Office 365 will automatically create the OST file that is used to store mailbox items such as emails, notes, contacts, attachments, tasks, and others. It has several benefits over other files, which make it preferable among users. Let’s look at them:

Recover lost mailboxes: OST files enable you to recover the lost mailboxes (in case of any damage that might have occurred to the Exchange Server or in case the server is down).

Automatic synchronization: If there is a connection issue between the user and the email server, it will not hamper your work with the OST file.. It will sync automatically as the connection is restored.

Stored in secondary storage: The OST file is a replica of the Exchange account’s mailbox stored on your computer’s hard drive. Hence, any damage done to the Exchange Server will not impact an OST file.

Access without an internet connection: This file allows you to access its content even if your internet connection is unstable.

Security and Reliability: Your OST file can keep your email data safe even if the server crashes or the Exchange Server has a problem.

These are the primary advantages of OST files that make them prominent over others. Users are usually concerned about accessing or opening the OST file in different versions of Outlook as per their requirements. Hence, we have covered the solution for opening the OST file in two sections: One with the same Outlook account and the other with a different one. Let’s look at the ways to implement it:
