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.
