Email and Other Accounts

In addition to supporting sign-in accounts like Microsoft accounts, work or school accounts, and local accounts, Windows 11 also lets you configure other accounts within a sign in account that can be used for other purposes. These include email, calendar, and contacts accounts that you will use with the Windows 11 Mail and Calendar apps and Microsoft accounts that you can use to sign in to Microsoft Store apps.
Configure an email, calendar, and contacts account
When you sign in to Windows 11 using a Microsoft account or a work or school account, the email, calendar, and contacts associated with it are also configured for use by the Mail and Calendar apps. This can be seen by opening the Settings app and navigating to Accounts > Email & accounts: you'll see your sign-in account listed under "Accounts used by email, calendar, and contacts."

But you can also configure any number of online accounts for use with the Mail and Calendar apps.
The question is whether you should use the Mail and Calendar apps or find more sophisticated solutions. And the answer is, it depends. Mail and Calendar both provide just basic functionality and are not appropriate for power users. But those with less expansive needs may appreciate their simplicity. You can learn more in the Mail and Calendar chapters. And even power users may want to configure accounts for use with these apps so that they can use the Windows 11 Share functionality to share information from compatible apps quickly via email.
To set up an online account for Mail and Calendar, click the "Add account" button in Email & accounts settings. The Add an account window appears.

Here, you will see the various online account types you can use with Mail and Calendar, and each choice will present a slightly different wizard that lets you initially configure the account. When you complete the wizard, you will see the new account appear in the list under "Accounts used by email, calendar, and contacts" alongside your Microsoft account (or other sign-in account).
Each account will also appear in the Mail and Calendar apps as well. (Some online accounts support only support certain services---email and contacts, for example, and not calendar---though the major accounts types support all three.)
Once you've added an account, you should further configure it.
This is true of the Microsoft account (or work or school account) you use to sign in to Windows too: it's likely that you will want to make some changes to the default configuration.
To do so, select the account under "Accounts used by email, calendar, and contacts" in Email & accounts settings to expand the view. Then, select the "Manage" button next to Account settings. The Account settings window appears.

From here, you can make the following changes.

Rename the account. Each account is given a name related to the email address of the account. But if that isn't descriptive or clear, you can rename the account in...
