What you need to know about adding accounts to Outlook

Adding an account to Outlook is similar to setting up an email account with Outlook. The main dif­fer­ence between the two processes is which protocol and address settings are used for the incoming and outgoing mail servers. These settings are de­ter­mined by your internet service provider. Ad­di­tion­al­ly, some email providers may require you to change certain settings on their website before you can add your email account with them to Outlook.

Here are some of the different types of account that you can add to Outlook:

  • Yahoo
  • Gmail
  • iCloud
  • Office 365
  • Exchange
  • IONOS
Note

To add a new account to Outlook, you typically need the password of that email account. If you have two-factor au­then­ti­ca­tion or other au­then­ti­ca­tion measures set up with your email provider, you’ll also need to have the cor­re­spond­ing secondary device ready. In order to complete the process of adding an account to Outlook, you’ll need to generate a special app password in the settings of the account you want to link.

How to add an email account to Outlook step by step

The steps you need to take to add accounts in Outlook depends on your internet service provider/mail provider and which version of Outlook you are using. You can choose between an automatic setup (not available for all email accounts) and a manual setup.

Below you’ll find detailed in­struc­tions for all Microsoft 365 Outlook versions as well as for Outlook 2021, Outlook 2019 and Outlook 2016. We’ll also explain how to add accounts manually and au­to­mat­i­cal­ly.

How to au­to­mat­i­cal­ly add an account to Outlook (desktop)

Re­gard­less of which version you are using, you can start by going to File. The Account In­for­ma­tion menu will appear. Now click Add Account. Type the address of the account you want to add and click on Connect.

If you have already added an email account in Outlook, it will be listed at the top of the account in­for­ma­tion.
Tip

The desktop version of Outlook offers users many options for per­son­al­iza­tion. Find out, for example, how to change the view in Outlook in a separate article in our Digital Guide.

To continue, enter your email address in the dialog window.

If prompted, enter your password. If adding the account was suc­cess­ful, a message will appear letting you know that the account has been added. Now, click Finish. You may need to restart Outlook in order to access the account that you’ve just added.

Note

If the email account hasn’t au­to­mat­i­cal­ly been con­fig­ured, check the account settings. The account may have ad­di­tion­al pro­tec­tion, such as two-factor au­then­ti­ca­tion, a security e-mail that you need to answer or a feature that blocks third-party ap­pli­ca­tions like Outlook. Some accounts cannot au­to­mat­i­cal­ly be added to Outlook. If this is the case, you’ll need to use the manual method.

How to manually add an account to Outlook (desktop)

For manual account setup, you need your login data and the data for the incoming and outgoing mail server of the email service. Similar to the automatic account setup, you’ll begin by clicking on File and then Add Account under Account In­for­ma­tion.

Select Advanced options and check the box Let me set up my account manually. Click Connect. Now, click on either your email provider or POP/IMAP.

Once you have selected the manual con­fig­u­ra­tion for adding a new account in Outlook, you can choose between several mail services and mail protocols.

Under Choose E-Mail Service, click on POP or IMAP or Internet E-mail and enter the address and server in­for­ma­tion of your mail provider. The data you need to enter depends on which service or protocol you select. (You can get this in­for­ma­tion from your mail provider.) For example, here is the in­for­ma­tion you would need to enter if you select IMAP:

Setting In­for­ma­tion needed Example
Incoming mail server Address of the incoming mail server imap.ionos.com
Incoming mail port Port to be used (Standard port: 143) 143
En­cryp­tion method (Incoming mail) Encyption protocol SSL/TLS (Standard: no en­cryp­tion)
Outgoing mail server Address of the outgoing mail server smtp.ionos.com
Outgoing mail port Port to be used (Standard port: 25) 25
En­cryp­tion method (Outgoing mail) En­cryp­tion protocol SSL/TLS (Standard: no en­cryp­tion)
Image: IMAP account settings
If you have selected IMAP as the mail protocol, you must enter the address, port number and en­cryp­tion method for both the incoming and outgoing server.

Only select the option Require login using Secure Password Au­then­ti­ca­tion (SPA) if it is supported by your provider’s mail servers or ex­plic­it­ly requested by your provider. After you are done entering every­thing, click on Continue.

Tip

If you are uncertain about the choice of trans­mis­sion protocol, we recommend taking a look at our article about IMAP and POP3.

To complete the process of adding an account to Outlook, enter your password and click on Connect.

Tip

In 2018, the option to add multiple accounts to the web version of Outlook was dis­con­tin­ued. If you only use Outlook on the web, you can still set up email for­ward­ing in Outlook, making it possible to have all your mails sent to one account.
