Outlook won't let me update my password.

For a GoDaddy-hosted mailbox that uses Microsoft 365/Outlook, the password cannot be changed from Outlook for Mac itself. The password must be changed with the email provider first, then updated in Outlook.

From the described setup:

• The mailbox is provided through GoDaddy (using Microsoft 365 as the backend).
• Outlook on Mac is only storing and using the password; it does not own or manage the account password.
• The error when trying to change the password inside the Microsoft account page in Safari indicates the password change is failing at the account-provider level, not in the Outlook app.

To resolve this for Outlook on Mac:

1. Change the password with the email provider
   • For a Microsoft 365 mailbox, the password must be changed through the account provider (in this case, GoDaddy/Microsoft 365 account portal), not from Outlook for Mac.
   • If the mailbox is a Microsoft 365 account, use the provider’s password-reset flow (for example, the Microsoft 365 password change page referenced in the documentation or GoDaddy’s account portal). If GoDaddy manages the tenant, their support may need to complete or unblock the password change.
2. After the password is successfully changed with the provider
   • Open Outlook for Mac.
   • Outlook will prompt for the updated password the next time it tries to sync.
   • Enter the new password when prompted so Outlook can connect using the updated credentials.
3. If the password still cannot be changed online
   • Because Outlook and the Mac itself cannot override provider-side security, the next step is to contact the account administrator or GoDaddy support and have them:
     • Verify the mailbox is active and not locked.
     • Reset the password from the tenant/admin side.
     • Confirm which sign-in method is required (password + SMS 2FA vs. Microsoft Authenticator).

Key points from the documentation:

• Password changes must be done with the email provider (Microsoft 365/GoDaddy), then updated in Outlook for Mac.
• Outlook for Mac only stores and uses whatever password the provider accepts; it cannot fix a failing password-change operation on the provider’s website.
