Overview: Desktop Outlook V.S. Outlook Web App(OWA)

Microsoft has developed both desktop Outlook and Outlook Web App (OWA) to manage personal emails, contacts, and calendars. While OWA is a browser-based solution, desktop Outlook is standalone software. Notably, Outlook on the web is free, but you have to pay for the desktop version.

However, for data backup in OWA, you need to download and use desktop Outlook, which encompasses all OWA features. Despite this, opting for desktop Outlook has several advantages. It offers customization options through the VBA developer in Microsoft Office, allowing you to personalize your Outlook experience. The desktop version also boasts additional icons and functions in the Ribbon that the web version lacks.

Here are some specific features that make desktop Outlook a preferred choice:

✍Customizable Menu:
Desktop Outlook stands out for its customizable nature. Utilizing the VBA developer, included with Microsoft Office, enables you to customize Outlook to your preferences.
✍Calendar and Task Integration:
With desktop Outlook, you can seamlessly schedule meetings and create tasks via email, adding a layer of intelligence to your personal and professional life.
✍Support for Multiple Email Accounts:
Desktop Outlook facilitates the use of multiple email accounts in one place, such as Gmail and Yahoo! accounts. Integration is straightforward by setting up a POP or IMAP account.
✍AutoArchive Settings:
The desktop version features a powerful AutoArchive function that automatically archives old emails, maintaining a tidy and organized inbox with minimal effort.

Given these advantages, it is highly recommended to opt for the desktop Outlook version, especially if you prioritize features like backup, a customizable menu, and the ability to log in with multiple accounts.
