Microsoft® Exchange: Change email address

You can continue to use an existing Microsoft Exchange account with all the e-mails and settings stored on the server with a different e-mail address for example if your domain name has changed. To change the e-mail address used, proceed as follows:

Log in to your IONOS account.
In the main navigation, click Menu in the top left corner and then click Email.

The IONOS account with the Email tile highlighted within the Menu.

If you have more than one email contract, select the contract in which you want to perform the desired action.

The Email page of the IONOS account with some example email contracts highlighted.

In the overview of your e-mail addresses, click on the e-mail address to be edited to access the settings.

An example email address is highlighted within the Microsoft Exchange Email Addresses page in the IONOS account.

In the settings, click in the line of the email address.

The clickable email address line is highlighted within the email address settings.

The Change email address page is displayed.

You can now edit the name part of the address (everything before the @ sign) directly in the text field.
If you want to use a different email domain, click Change Domain and select the desired domain.

The Change Domain link is highlighted within the change email address settings page.

Click on Save. Your email settings will now be updated. You will be able to use your new address within a few minutes.

As soon as the change takes effect, your mailbox will only be accessible with the new address.
