 . Email Migration  . Migrate to Office 365: How to Migrate Email to Office 365

If you’re new to Microsoft Office 365, you might be a little bit worried about how to migrate email to Office 365 from another email provider like Gmail or Yahoo! Well, don’t worry at all! In fact, it’s a very simple and quick process. So let’s start!

Step 01: Get ready to migrate to Office 365

In order to migrate to Office 365, you need to have the following credentials at hand:

  1. the credentials for your old email account (username, password and name of your mailserver)
  2. the credentials for your Office 365 account

👉 If you have the credentials for both accounts at hand, continue with step 02. Otherwise, keep on reading 😉

Don’t have your Office 365 credentials?

When you register with a hosting provider, you will usually receive your access data in the form of an email or a data sheet. It’s notoriously easy to lose things like this, so the first piece of advice is to log into your hosting provider’s customer center and look for your credentials there. For large hosting providers, a quick Google search for “your hosting provider credentials” can help you find where to get your email account credentials.

➡️ If you still do not find your credentials, please contact your hosting providers support.

Don’t have the credentials for your old account?

Know your Office 365 credentials? Skip to step 02 ➡️

Usually, your Office 365 credentials are stored in your local computer, so it’s quite likely that you don’t have them at hand when you wish to migrate email to Office 365.

In case you don’t know your username, use the Microsoft Username Recovery tool.

A detailed description on what to do in case you forgot your username can be found here.

Step 02: Setup your Office 365 account to migrate email

Depending on the type of your Office 365 account, you might have to setup your account in order to be able to migrate email to Office 365.

Do I have to change the settings of my Office 365 account?
