How to Migrate Gmail to Office 365?

Today, nearly everyone uses Gmail as a primary tool of email communication. Gmail users can access Google's free cloud services, including email, contacts, calendars, videos, files, and more. On the other hand, Microsoft 365 is a cloud-based service offered by Microsoft. There are various advantages of using Microsoft 365, such as:

• It has cutting-edge protection and safeguards mechanisms.
• Microsoft 365 accounts are managed centrally by those in charge.
• Extra storage space is available with a paid Microsoft Microsoft 365 online subscription.
• One Note, Outlook, Skype for Business, and many more Microsoft applications are included in the Microsoft 365 software suite.

Due to these and other benefits, users plan to migrate from Gmail to Microsoft 365 or Office 365. However, there is no direct way to just migrate from Gmail to Microsoft 365.
