Office 2013 Asking for Password 365 Exchange - no reason just started happening
So todays issue revolves around office 2013 and exchange 365 accounts.
I had an issue with a user's machine that just kept asking for the password but would not accept it, the login box kept coming back up. Turns out 2013 uses an old auth method so we need to force it to use the new method.
So using regedit you need to add the below key
Registry key Type Value
HKEY_CURRENT_USER\Software\Microsoft\Exchange\AlwaysUseMSOAuthForAutoDiscover REG_DWORD 1
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity\EnableADAL REG_DWORD 1
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity\Version REG_DWORD 1
Enable modern authentication for Office 2013 clients
Close Outlook.
Copy and paste the following text into Notepad:
textWindows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Exchange] "AlwaysUseMSOAuthForAutoDiscover"=dword:00000001 [HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common] [HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity] "EnableADAL"=dword:00000001 "Version"=dword:00000001
Save the file with the file extension .reg instead of .txt in a location that's easy for you to find. For example,
C:\Data\Office2013_Enable_ModernAuth.reg
.Open File Explorer (formerly known as Windows Explorer), browse to the location of the .reg file you just saved, and then double-click it.
In the User account control dialog that appears, click Yes to allow the app to make changes to your device.
In the Registry Editor warning dialog that appears, click Yes to accept the changes.
