Setting Up Microsoft Exchange 2013 in Outlook (Windows)
These instructions are only valid for domains that you have set up at IONOS
Microsoft Outlook versions from 2016 onwards no longer support manual setup of Exchange mailboxes. We recommend that you set up the Microsoft Exchange 2013 account using the autodiscover feature as described in the Outlook Configuration guide below. If the setup fails through autodiscover, set up the account in Outlook manually instead.
Notes
Before setting up your account in Microsoft Outlook, check whether an autodiscover record is created in the DNS settings of your domain. If the autodiscover record is created with the value adsredir.1and1.info, you must delete the record. Then create a new autodiscover record with the value adsredir.ionos.info. For more information, please see the following article:
Checking the Autodiscover Settings of Your DomainIf you order a domain from a third-party provider, make sure that an Autodiscover record is created in your domain's DNS settings.
If you re-order the domain or change the DNS settings, it may take some time for the DNS settings to update.
If you have previously configured a Microsoft Exchange 2013 mailbox, you will need to set up a separate Outlook profile for the new Microsoft Exchange 2013 account. In addition, enable the prompt that allows you to choose the Outlook profile. This will be displayed after activation when Microsoft Outlook is started.
If you are using a version of Outlook that is deployed as part of Office 365 and you are presented with the Office 365 login window when you set up the Microsoft Exchange 2013 account, follow the instructions in the following article:
