New outlook app not recognizing my password

Question

I have a Microsoft 365 subscription and use the New Outlook app for my business email, hosted by the server for my business domain. The domain was suspended because the primary credit card had expired, so 2 days later I had the mail server make my secondary card primary, and my mail was back online. I had Outlook set up for IMAP, but it didn't download the new email after the credit card expired. I worked with the mail server and changed the email password. I rebooted the laptop (Windows 11) and when I launched Outlook, it autofilled my email address and prompted me for my password. I tried the new password, the old password, the Microsoft general password. Nothing works. I can access my mail on a browser, but I need to be able to access Outlook (mail, calendar, people, etc.).

Answer 1

Use the password that works in the browser for the business mailbox and update it in Outlook; Outlook will not accept any other password once the server-side password has changed.

Then try the following steps in order:

1. Confirm the account password
   • Sign in to the mailbox in a browser using the same email address Outlook is configured for.
   • If sign-in fails there, reset the mailbox password with the mail provider first, then try Outlook again.
2. Update the password in New Outlook
   • In New Outlook, select the icon next to the email account name.
   • When the sign-in pop‑up appears, select Continue.
   • Enter the same password that works in the browser and complete the prompts.
   • If the provider requires an app password (common with IMAP and 2FA), follow the provider’s instructions to generate an app password, then paste that into Outlook when prompted. The message may look like: “Please create an app password for Outlook on your email provider's site.”
3. If Outlook still will not connect
   • Remove the IMAP account from New Outlook and add it again using the working password (or app password) following the provider’s IMAP settings.
   • Ensure the account type and server settings match what the mail host requires.

If using classic Outlook instead of New Outlook, and it keeps asking for a password after the change, update the stored password in Outlook as described in Change or update your email password in Outlook for Windows.
