HISTORY OF THIS PROBLEM:
We've probably seen this problem half a dozen times or so in the last year and every time I came across it I could never find a fix no matter how much Googling I did. Finally I have the solution (or at least the solution that's worked for me)...

outlook need password no prompt

This problem for me was always with Outlook 2010 and 365 mailboxes. The initial setup of Outlook would work fine and Outlook WOULD connect. However after the initial setup you close Outlook and when you open it again (2nd time onwards) Outlook would say need password but would never display the normal username & password box. So basically there is nowhere to type in the needed user credentials and Outlook never connects.

HOW TO FIX OUTLOOK NEEDS PASSWORD BUT NO PASSWORD PROMPT APPEARS:
1. Click Start, click Run, type regedit in the Open box, and then click OK.

2. Locate and then select the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft
\Office\14.0\Common\General

3. On the Edit menu, point to New, and then click DWORD (32-bit) value.

4. Type DoNotQueryUserNotificationState, and then press ENTER.

5. Right-click DoNotQueryUserNotificationState, and then click Modify.

6. In the Value data box, type 1, and then click OK.

7. Exit Registry Editor.
