This article should help users to change or update their password to connect to their mailbox in Office 365 Outlook.
Please note that you cannot change your mailbox password through the Outlook app interface. First, you must change/update the password for your email provider. For example, Microsoft 365, Outlook.com, Apple iCloud Mail, Gmail, etc. Only after that, you can update the password to connect to the email service in Outlook.
Change Your Microsoft 365 Account Password
If your mailbox is hosted on Microsoft 365 (Office 365) and you use one of the Microsoft subscriptions, you need to change the password for your Microsoft 365 account. This will change your Outlook password as well.
- Sign in to https://www.office.com/ with your credentials, click on the upper right corner of your profile, and select View Account;
- Select Change Password, on the page that opens (https://myaccount.microsoft.com/?ref=MeControl);
- In the new window, enter the old password, set a new one, and confirm;
- Save the changes;
- Close Outlook;
- The next time when you connect, Outlook will ask you for a password;
- Use a new password.
Hint. If you forgot the password for your work account in Microsoft 365, or it does not work, you can reset the password through the self-service password reset portal.
If you are using a different email provider, update your password in your account management interface or through the web-based email service. After that, you need to change the saved password in Outlook.
Change Saved Email Password in Outlook 365
If your Outlook is configured to connect to an external email provider (Gmail, Apple, Yahoo, etc.) and your Outlook is configured to connect to a mailbox using POP3/IMAP protocol, you need to update the saved password in the Outlook connection settings.
Tip. Check the article How to setup Gmail account in Outlook.
Open Outlook and go to File > Info > Account Settings > Manage Profiles > Email Accounts.
Select your account on the Email tab and click Change.
In the window with the mailbox connection settings, update your password in the Logon Information section.
Click the Test Account Settings button and check if the connection to the mail server task is completed successfully. Green checkmarks indicate that the test was successful.

Note. For your Gmail mailbox, you need to use app-specific password instead of your Google account password.
If Outlook says you are trying to connect with invalid credentials, try to remove the cached credentials in Windows Credential Manager.
