For Microsoft Exchange 2013
Learn how to set up your Microsoft Exchange 2013 account in Microsoft Outlook 2016.
As a 1&1 IONOS customer, your email settings should be automatically detected by Outlook, after supplying your email account and password.
If you encounter any problems during the automatic configuration, you can Set up Microsoft Exchange 2013 Using Outlook Configurator.
From the Windows Start Menu, open the Control Panel.
In the Control Panel window, search the box at the top-right for "mail" and double-click Mail (32-bit).
Click Show Profiles.
Choose Add. Now enter any name for your account profile. This name is used to distiguish your mail accounts from each other. Click OK to continue.
Enter Your Name and E-mail Address. Enter your Password twice and then click Next.
If you receive a warning, tick the box to not warn you in the future and click Allow for the email setup to be downloaded automatically using the autodiscover settings.
Enter you password again in the pop-up window and click OK.
Once Outlook has completed verifying the setup, click Finish.
Once you are connected to the Exchange server, you will see Connected to: Microsoft Exchange at the bottom-right of Outlook.
Outlook will then synchronise your Microsoft Exchange 2013 account for the first time. This can take several minutes, depending on how many emails, calendars and contacts are stored in your account, as well as your internet connection speed.
