How to Change Primary Account in Outlook on Windows 11
In New Outlook, go to Settings , then Accounts, select Email accounts, choose your account, click Manage, and set it as primary. For Classic Outlook, you must create a new profile via the Control Panel Mail applet, adding your desired primary account first.
Prerequisites
Before you change your primary account in Outlook, gather your account passwords and back up your data files. You also need administrator access.- A stable internet connection.
- Your email account passwords.
- A backup of your data files (.pst or .ost).
- Administrative access to your computer for profile changes.
Why change your primary account?
Your primary account acts as the main identity for Outlook, managing your calendar, contacts, and privacy settings. Consider changing it if you have a new main email address or need to switch your default identity for work or personal use.
What happens when you are done?
Once finished, Outlook will restart. The new account becomes your primary one. Your old emails will remain, but your calendar and contacts will now sync with the new primary account settings.
