O365 Outlook keeps asking for Password but not able to enter

Hi all,

Problem: Outlook keeps saying “Need Password”, not allowing to enter password (password window just flashing), and of course, not sending/receiving emails. Issue is in Windows 10 + Outlook 2016 + Office 36 email.

I did following troubleshooting steps on many computers, no improvements, it may work a 2 days or others , and issues comes back:

  • Disconnected any email account connected with Windows and restarted

  • Removed any credentials saved on Windows Credential for problematic email and restarted

  • Ran following PowerShell commands as Admin and restarted:

New-ItemProperty -Path HKCU:\Software\Microsoft\Office\16.0\Common\Identity -Name DisableADALatopWAMOverride -PropertyType DWORD -Value “0x1” –Force

New-ItemProperty -Path HKCU:\Software\Microsoft\Office\16.0\Common\Identity -Name DisableAADWAM -PropertyType DWORD -Value “0x1” –Force

New-ItemProperty -Path HKCU:\Software\Microsoft\Office\16.0\Common\Identity -Name EnableADAL -PropertyType DWORD -Value “0x1” –Force

Randomly it may works by restarting the PC and issue comes back in 1 or 2 days.

My resources: Email service - Office 365 and Email Client - Outlook 2016

hello All, Faced the same issue , steps I followed to solve it.

  1. Remove all microsoft related from credential manager

  2. Go to remove apps - click on the microsoft o365 --> Change --> Repair without internet option.

Open the Outlook it worked for me.

Please note, 1st try wout deleting profile. If above steps not work then you hv to delete profile from Mail -> accounts -> and proceed ahead with above steps again.
