Outlook No Longer Accepting Password (Windows)


Whenever I open Outlook, I am prompted to enter my username and password.


  • Windows 10
    • Outlook 2016
    • Outlook 2019


This can happen either when the account credentials are not stored by Outlook, or if a security feature has been enabled that always prompts for logon credentials.


  1. Enter your credentials.
  2. If the logon prompt has a box below the password field to Remember Password, click it to place a checkmark in the box. Click OK.
  3. If there is no box:
    1. Click OK to login.
    2. Click File.

    9. Uncheck Always prompt for logon credentials.
    10. Click OK.
    11. Click Next > .
    12. Click Finish.
    13. Click Close.
