For efficient email communication, both individuals and businesses rely on a robust email management system. A dependable email platform is essential for organizations to thrive in the highly competitive landscape of information technology. Here are some key features that users typically seek in an email platform:

High email data availability

Users expect their email platform to provide instant access to their emails. Many email management applications support multiple account types from various email servers, and these mailboxes should remain active whenever the application is open. Users should be able to send and receive emails seamlessly without any hassle.

Email Security

Email communication over the internet relies on protocols that facilitate fast and straightforward messaging while incorporating security features. Additionally, email management applications often include security measures to prevent the delivery of malicious or spam emails. These applications may proactively scan emails and their attachments for potential threats before they are opened or displayed in the mailbox.

Cross-platform compatibility

While web-based email services typically support email addresses associated with their own platforms (e.g., Google supports Gmail, Yahoo supports Yahoo Mail, Microsoft supports Hotmail), professional email clients like Outlook are designed to be more versatile. They can accommodate email accounts from various platforms, providing users with a unified and comprehensive email management solution.

Advanced collaborative business services

In addition to email communication, a comprehensive email manager should offer a range of features to support various business tasks. These may include contact management, calendar and event handling, archiving, backup capabilities, and more. These additional features help users and businesses efficiently manage their communication and productivity needs within a single application.

People have a deep affinity for the MS Outlook email application because it embodies the parameters mentioned earlier. Microsoft Outlook has come a long way, starting with Outlook for MS-DOS and evolving into the highly robust and intelligent MS Outlook 2016 version, which has left a lasting impact on users' email and productivity experiences.

Microsoft Outlook Provides Exclusive Email Storage System

MS Outlook is closely integrated with MS Exchange Server technology, offering a wide range of features, including exceptional email management, calendaring, task scheduling, and contact management services. It offers two highly useful email formats: Outlook Data File (.pst) and Offline Outlook Data File (.ost). These formats simplify email access whether you're connected to the Exchange Server, working on a standalone machine, or both.

Among these two file types, the Offline Outlook Data File (.ost) plays a crucial role by creating a local replica of email items stored on Exchange mailboxes. This local replica ensures uninterrupted email access even during periods of Exchange Server disconnection. However, the automatic creation of OST folders on your hard drive can sometimes be disadvantageous, especially when there is a need to save OST backups to a different drive partition or a separate hard disk.

The precise location of the OST file can vary slightly depending on the version of the Windows operating system being used. Here's a breakdown of the OST file storage locations for different Windows OS versions:

  • OST file location in Windows 10, Windows 8/8.1, Windows 7, & Windows Vista C Drive: \Users\%username%\AppData\Local\Microsoft\Outlook (For MS Outlook 2010 or Above)
  • OST file location in Windows XP

C Drive: \Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook

Changing the default location of an OST file is possible through the MS Outlook email client. However, it's important to exercise caution when making this change, as it can sometimes lead to unpredictable behavior in MS Outlook.
