In this blog, We learn about the Yahoo Mail and Office 365 account and their features. And we also know, How to migrate Yahoo Mail to Office 365 account. Lets start.

In the modern world, emails are a valuable way to talk to people. Every area of business is being shaken up by technological advances, causing web-based email tools to set their standards and come up with new ones to meet the needs of the next generation of users. Today, users can use any email platform they want, whether they are businesses or people. As technology improves, users are being forced to ditch their old email services and switch to better web-based email clients.

Gartner Research from 2016 and 2017 found that almost 80% of Yahoo users are considering switching to other web-based email apps. Microsoft Office 365 was a name that came up a lot during this research. Yahoo Mail fails miserably at meeting the needs of business and personal users in the 21st century.

Why Users Move from Yahoo Mail to Office 365 (Microsoft 365)?

Before we talk about how to switch from Yahoo mail to Outlook, let’s talk about why more and more Yahoo mail users are switching to Office 365.

Flexibility: Office 365 has different plans for individuals, small businesses, and large businesses. Businesses can easily grow by using their plans or adding new ones as they grow.

Functionality: Most Office 365 plans give you more than just a mailbox. Users also get Excel, PowerPoint, One Drive, and other Microsoft programs and services. Even if these applications aren’t included in the package, they are easy to add as add-ons.

Security: Microsoft has some of the most advanced features to keep its users safe. Office 365 has a lot of security features that are usually only found in enterprise suites.
